to their interchanges with I-285. The only section of major interstates that was not rebuilt in the project was I-85 between the Brookwood Split to present-day Georgia 400. The Georgia Department of Transportation opted to build a new viaduct carrying the new 10-lane I-85 just north of the original I-85 alignment and downgraded the original alignment to Georgia State Route 13. The construction of the Tom Moreland Interchange, replacing the cloverleaf interchange at the junction of Interstate 85 and Interstate 285 on the northeast side of Atlanta, began in 1983. The first flyover ramp opened in 1985 and the interchange was completed in 1987. The other intersection of I-285 and I-85 on the southwest corner of Atlanta was originally constructed as a concurrency in the 1960s. When completed in 1989, the newly widened I-285 and I-85 had separate parallel roadways. The final phases of construction were on the Downtown Connector. Work on the Connector began in 1984. The project widened the Connector to 10 lanes, which included the design and construction of 55 bridges over the connector. GDOT policy mandated that there were never fewer lanes open during construction as existed before construction which added to the cost and time devoted to the Downtown section. The final segment of the Downtown Connector opened in November 1988. While not officially part of Freeing the Freeways, over the next few years into the early 1990s, several of the suburban interstates would be widened including I-75 in Cobb County from Windy Hill Road to I-575 and I-85 in Gwinnett County from I-285 to SR 316. I-285's northern arc would get another lane in each direction. All these projects contributed to Atlanta having world class infrastructure and being selected to host the 1996 Summer Olympics. I-75 and I-85 (as well as their Downtown Connector concurrency) were built with provisions for high-occupancy vehicle lanes (HOV lanes) including dedicated exits and on-ramps at Northside Drive, Lindbergh Drive, Williams Street, Piedmont Avenue, Memorial Drive, and Aviation Boulevard. In 1989, the Georgia Department of Transportation estimated it would cost just under $430,000 to convert a lane in each direction for 21.3 miles of I-85 to HOV lanes. The first HOV lanes to open were on I-20 from the Connector east to I-285. In June 1996, in anticipation of the 1996 Summer Olympics, HOV lanes opened on I-75 and I-85 from Aviation Boulevard on I-75 north to the Chattahoochee
