BALTIMORE As night falls on Baltimore on Tuesday, thousands of police and National Guard troops fanned out to enforce a new curfew and prevent further violence as the mayor fended off criticism that she responded sluggishly to a night of rioting, looting and fires. 
 
 More than 3,000 police from Maryland, New Jersey and the District of Columbia, and National Guard members in helmets, took up posts in front of businesses and hospitals in Baltimore a day after the worst rioting in the United States in years. 
 
 Shops were looted, buildings burned to the ground, 20 officers injured and police arrested more than 250 people in the violence that erupted following Monday's funeral of a 25-year-old black man who died in a hospital on April 19 a week after sustaining injuries in police custody. 
 
 The death of Freddie Gray gave new energy to the public outcry that flared last year after police killings of unarmed black men in Ferguson, Missouri; New York City and elsewhere. 
 
 For nearly a week after Gray died from a spinal injury, protests in Baltimore had been peaceful and Mayor Stephanie Rawlings-Blake said she acted cautiously on Monday because she wanted to avoid a heavy-handed response that would incite more violence. 
 
 "It's a very delicate balancing act, when we have to make sure that we're managing but not increasing and escalating the problem," said Rawlings-Blake, 45, an African-American and Democrat who grew up in the city 40 miles (64 km) from Washington, D.C. 
 
 Maryland Governor Larry Hogan said he had called Rawlings-Blake repeatedly Monday but that she held off requesting the National Guard until three hours after looting started. 
 
 "The mayor of Baltimore had the city of Baltimore police on the ground. Quite frankly, they were overwhelmed. All the rest of the (boots) on the ground came from us," the Republican governor said the day after declaring a state of emergency in the largely black city. 
 
 Rawlings-Blake imposed a one-week curfew but stressed the need to respond in a way that did not incite more violence. 
 
 Bars and restaurants were shutting down early since they did not expect clients due to the 10 p.m. curfew for all adults, which will last the rest of the week. 
 
 "We have no exceptions other than for medical or coming and going from work. We will be stopping people who are out after curfew. We are taking that seriously. We don't want to engage in any forceful action," Police Commissioner Anthony Batts told reporters. 
 
 Peaceful protesters marched through some Baltimore streets on Tuesday, but there was no sign of the rock- and brick-throwing that set off a night of looting and arson that burned 19 buildings and left one person in critical condition. 
 
 "They tore the city down last night, and today we're trying to rebuild it again," said Perry Hopkins, who formed a line of men from the community separating police from the crowd in the afternoon. 
 
 Volunteers armed with brooms cleaned up debris from burned out and looted buildings in the city of 620,000 people, where schools, many businesses and some government offices closed until security improved. 
 
 The security crisis disrupted the city's daily routines. In a rare move, the Major League Baseball game between the Baltimore Orioles and Chicago White Sox will be played as scheduled Wednesday but closed to the public. 
 
 Acrid smoke hung over the streets and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives said it was sending two teams to Baltimore to investigate the multiple blazes on Monday night. 
 
 Gray was arrested on April 12 while running from officers. He was taken to the police station in a van, with no seat restraint and suffered a spinal injury. 
 
 Six officers have been suspended, and the U.S. Justice Department is investigating possible civil rights violations. 
 
 'DELICATE BALANCING ACT' 
 
 "There's no excuse for the kind of violence that we saw yesterday," said President Barack Obama, who said he spoke to the governor and the mayor. "It is counterproductive." 
 
 Obama also said at a news conference the problems in places such as Baltimore were not new and need to be addressed by everyone. 
 
 "We can't just leave this to the police," Obama said, adding that "we as a country have to do some soul searching. This is not new. It's been going on for decades." 
 
 Almost a quarter of people in Baltimore live below the poverty line and decayed, crime-ridden areas of the city inspired the gritty television police drama "The Wire." 
 
 Monday's ransacking of stores, pharmacies and a shopping mall and clashes with police in riot gear was reminiscent of rioting in Ferguson, Missouri, in 2014 after authorities declined to indict a white police officer who shot dead an unarmed black teenager. 
 
 Police in Ferguson came under intense criticism last year for quickly adopting a militarized posture, using armored vehicles, showing heavy weapons and using tear gas. 
 
 Baltimore police Captain John Kowalczyk told reporters that the city had prepared for protests by teenagers on Monday. But as the violence increased, older people were involved. 
 
 "When we deployed our officers yesterday, we were deploying for a high school event," Kowalczyk said. "I don't think there's anyone in the country that would expect us to deploy with automatic weapons and armored vehicles to an event with 13- 14- and 15-year-olds."

 Quality bicycling trails help define a region’s quality of life. They provide health and transportation benefits. They’re fun and becoming a major tourism draw for the places with compelling facilities. Trails appeal to teenagers, millennials, families, and retirees. Unfortunately, the Baltimore region’s combination of trails is far inferior to Washington’s, Philadelphia’s, New York’s, Boston’s, and we are falling behind Pittsburgh. These other northeastern metros have invested far more and have developed networks and high profile trails. Our region should at least try to be in the same league. The good news is–the six projects identified below, collectively, would cost less than one basic highway interchange and help Baltimore take a giant leap forward. 
 
 Other Northeastern Metros are investing in their trail systems. Here are a few of their investments.

 Right now, Baltimore has a handful of average to good trails, but mostly they are one-offs, with little relation to one another. Imagine if I-95 didn’t connect to the 695 Beltway and 695 didn’t connect to I-83 or 795. These highways by themselves would be useful, but the connected network is exponentially more beneficial. Over the next decade, the Baltimore region should connect its primary trails. It should also develop a few marquis trails that show off the beauty of our city, watershed, and region. Here are six projects that would create the backbone of a connected regional trail network reflective of our affluent region. 
 
 Project 1–Gwynns Falls/Middle Branch Trail to BWI/B&A Trail. (Shown in orange) 
 
 Estimated cost and length: $10 million, 10 miles (7 miles shared with project 6) 
 
 Sister trail: Guadalupe River Trail, San Jose, CA 
 
 Project 1, from the Middle Branch Trail’s end in Baltimore’s Cherry Hill Park, to the BWI trailhead-at the BWI rail station, is approximately 10 miles. By completing this missing link, the trail network could continuously reach from Mt. Washington in Northern Baltimore City to Greater Annapolis, a roughly forty mile spine. 
 
 There is good news. It’s feasible. The Patapsco River and Stony Run tributary valleys provide virtually continuous right-of-way, which would make the trail relatively free of street crossings, with little need for property acquisition or easements. 
 
 There are more reasons to like this project. The river valleys provide great scenery of Baltimore’s most significant river. There are marshes, riverscapes, forests and lots of other features that make for a scenic recreational trail. If project 1 is completed, the trail will connect job centers, neighborhoods, and the rail transit system. 
 
 Project 2–Baltimore Trail “Beltway” 
 
 Estimated cost and length: $10-20 million, 15 miles of new trail to make 35 mile loop 
 
 Sister trail: Beltline, Atlanta 
 
 This project is the urban trail version of I-695. It fills in the gaps that would enable a continuous 35 mile loop in Baltimore City. To complete the loop a little over 10 miles of trails would need to be constructed and some additional upkeep on existing trails would improve the experience. This project is being spearheaded by the Rails to Trails organization, headquartered in Washington DC. 
 
 This project may not be as logistically easy as Project 1 because it loops through neighborhoods and requires cooperation with CSX and BGE in a few places. However, a theoretical right-of-way has been established and with a little cooperation, this project is feasible. 
 
 There are lots of reasons to like this project. It has many of the benefits of Atlanta’s Beltline, but with a fraction of its price. The Baltimore Trail “Beltway” is a home run waiting to be hit because it covers so many bases. Tourism, health, better transportation, recreation, and economic development are expected benefits of its completion. 
 
 Project 3–Jones Falls Trail to Torrey C. Brown Trail (Shown in red (Towson Run Trail) and then blue) 
 
 Estimated cost and length: $15-20 million, 14 miles (This includes Towson Run Trail Project) 
 
 Sister Trail: Rock Creek Trail, Washington DC and Montgomery County, MD 
 
 Project 3 connects a trail gap between Mt. Washington in Baltimore City and Hunt Valley, Baltimore’s most northern suburb. The completion of the project would also fill in the missing vertebrae in a trail spine and create a continuous link from Baltimore’s Inner Harbor to York, Pennsylvania. 
 
 The Torrey C. Brown trail is, arguably, the Baltimore region’s most popular paved trail. It is heavily used and is part of the Rails to Trails Hall of Fame, but it is isolated. 
 
 This connecting project would have to bisect suburban neighborhoods and would likely contain some street routes in spots (with buffered lanes). The bad news is there is no obvious path north of Towson, but the good news is there are many possible routes the trail could take. This project could be challenged by NIMBYism and crossing over the 695 Beltway may be a challenge depending on the course. 
 
 There are many reasons this is a good project. We will start with the East Coast Greenway (ECG). The ECG plan is a continuous trail from Maine to Florida. Project 3 fills a key gap in the ECG. Another good reason is access. By extending the mostly rural Torrey C. Brown Trail into the inner suburbs and ultimately the city, far more people will be within reach of a super trail. 
 
 Project 4–Middle Branch Loop Trail (Shown in yellow of the Project 1 map) 
 
 Estimated cost and length: $4-10 million, 3 new trail miles, 4 total miles (If a trail right-of-way can be constructed on the Hanover Street Bridge replacement, the trail cost will be on the lower end) 
 
 Sister Trail: Lake Union Loop, Seattle 
 
 The Middle Branch Trail Loop, if completed, will hug the water and help connect Baltimoreans and visitors to the city’s waterfront. The Middle Branch is destined to be the new home for Under Armour. A premier waterfront recreational amenity would be a great cultural compliment between the company, the city, and the water. 
 
 The challenge is adding a trail facility on a little-used century-old CSX owned swing bridge and the heavily used Hanover Street Bridge. Furthermore, Under Armour would need to be supportive of a public facility and not seek to privatize the space to the water’s edge. 
 
 An urban waterfront loop that utilizes two large bridges may be a big attraction because it’s a unique design that’s rarely implemented. Also, a trail running across a former train bridge adds historical value. 
 
 Project 5–The Towson Run Trail (shown in red) 
 
 Estimated cost and length: $6-8 million, 5 miles of new trail 
 
 Sister Trail: Capital Crescent Trail, Washington DC and Montgomery County 
 
 This project would connect the Jones Falls Trail (Shown in brown), the Falls Road Light Rail station, and Lake Roland with Towson University and Downtown Towson and its “bike beltway.” 
 
 Building a trail adjacent to the Towson Run stream into the center of the university and to the business district appears to be feasible, but might face some NIMBY opposition in the area between Lake Roland and Charles Street. The trail may need a bridge to cross Lake Roland. 
 
 This is a good project because Towson, the Baltimore County government seat and home to over 55,000 people, has few recreational bicycle facilities. Linking Towson via the valley of the Towson Run Creek into the Jones Falls Trail would help solve that problem, while tying Towson into the regional trail network. This project could fill a gap in the East Coast Greenway Project and share the first five miles of Project 3. 
 
 Project 6–The Patapsco Trail (shown in dark yellow on the Project 1 map) 
 
 Estimated cost and length: $15-20 million, 16 miles of new trail and 18 total (7 miles shared with Project 1) 
 
 Sister Trail: Schuylkill River Trail, Philadelphia 
 
 This project is identical to Project 1 for about the first seven miles, sharing the Patapsco River Valley at its source in the Middle Branch. Project 1 makes a southerly turn to connect with the BWI Trail. Project 6 continues northwest along the Patapsco Valley paralleling the river. It will feed into the Grist Mill Trail and then extend into historic Ellicott City. 
 
 This project appears logistically easy because of existing public right-of-way next to the river. There are a few places the trail will likely have to go underneath major roads. There will be some wetlands the trail may pass through. 
 
 Project 6 is a trail with tourist and transportation benefits. It would connect charming historic Ellicott City with downtown Baltimore, while taking a scenic, flat, and relatively direct path along the river. It would provide a great day trip in either direction. 
 
 Regions in the Northeast and across the US are investing in their trail networks and marquis trails. They know that quality of life amenities are a major component to region attractiveness and competitiveness. The Baltimore region’s trails are inferior to many of our competitors and the gap is widening. It may be a leap to propose more trails when some of our major existing trails are not well designed and are in poor repair. However, the workforce of the future and tourists will want quality trails. The state, counties, corporations, or even wealthy individuals should help fund it. 
 
 It is time for Baltimore to develop a regional trail plan and invest.

– Some Baltimore residents aren't standing by idly in the mess after yesterday's violence. Volunteers took to the streets today to clean up their "Comeback City." Gawker has culled a series of tweets showing images of helpers picking up debris on the roads and sidewalks, sweeping up in front of a burnt CVS, and handing out refreshments to other volunteers and police monitoring today's activities. "I'm just here to help out, man," one local sweeping broken glass in front of the CVS tells Reuters. "It's the city I'm from."
