as the beginning of Shore Line East as a true bidirectional system. Several existing express trains also began to stop at Guilford. A pilot of weekend service was run from November 17, 2007, to December 30, 2007, with six "Shopper's Special" round trips from Old Saybrook to New Haven. The trains were scheduled to connect with similar Metro-North specials at New Haven. Year-round weekend service began on July 4, 2008, with 9 daily Old Saybrook – New Haven round trips on weekends. No weekend service was run to New London, but weekday service was increased by the addition of cross-honoring of multiple-ride and monthly tickets on two Amtrak trains. The major obstacle preventing full New London service was the bridge over the Connecticut River between Old Saybrook and Old Lyme. The drawbridge section is closed for a certain period of time to allow trains to pass, which prevents large boats from passing under. The Marine Trades Association opposes additional service, which would mandate more bridge closings. The 2003 agreement with Amtrak limited weekday traffic over the bridge to 2 SLE and 39 Amtrak trains until 2018, although it was revised in 2010 and 2013. Since 2003, New London had been served by cross-honored Amtrak trains plus one or two dedicated SLE round trips. On February 16, 2010, an additional round trip was extended to New London. Three more were extended on May 10, 2010. However, advocates for full service to New London said that then-governor Jodi Rell failed to deliver on promises to New London, with one newspaper columnist writing that "she seems incapable of standing up to the marine trades lobby" regarding the bridge openings. In July 2012, then-governor Dannel Malloy announced that five weekend round trips would be extended to New London beginning in April 2013. However, the extension was dependent on ongoing negotiations with the marine industry over mandated closings of the Connecticut River bridge. Two weekday midday trips were added in May 2013, while weekend service began on June 1, 2013, after the application for additional bridge closings was approved by the state Department of Energy and Environmental Protection. By July, New London represented 26 percent of weekend ridership. In December 2013, the state announced that ridership was up 35 percent for the year as a result of the increased service. From 2009 to 2014, monthly New London ridership increased from less than 1,000 monthly passengers
