Interstate 35E will be shut down in Oak Cliff from Friday night until Monday morning as crews take out the Beckley Avenue overpass as part of the $666 million Southern Gateway project.
It's the second shutdown of all main lanes on the freeway in as many months connected to the three-year project. Crews took out the overpass at Eighth Street in June.
Traffic in both directions will be diverted to the freeway's frontage roads starting at 9 p.m. Friday. To help keep traffic moving, the Zang Boulevard and 12th Street overpasses will also be closed this weekend. The main lanes will reopen at 5 a.m. Monday.
Zang and 12th Street and Clarendon Drive will serve as the detour for traffic on Beckley -- where the overpass rebuild will take 18 months.
Also in conjunction with the Southern Gateway project, Eighth Street is reduced to one lane in each direction between Jefferson Boulevard and I-35E from 9 a.m. to 3:30 p.m. Wednesday, Thursday and Friday.
The Southern Gateway project has already claimed other parts of the freeway. High occupancy vehicle lanes were closed in March and will not reopen until the Southern Gateway connection to downtown Dallas is completed in 2021. And the Fleming Place underpass at I-35E was closed in early June. It will not reopen.
The Texas Department of Transportation and local officials broke ground on the 11-mile-long Southern Gateway on Feb. 28. The project will widen I-35E from four lanes to five in each direction and give the interstate two reversible, non-tolled express lanes from Colorado Boulevard to U.S. 67.
Officials said the project would help mend the areas around the freeway. A deck park -- similar to Klyde Warren Park over Woodall Rodgers Freeway -- is planned over the freeway near the Dallas Zoo. The park is a partnership between the city of Dallas, the Regional Transportation Council and private donations.
In addition to the I-35E improvements in Oak Cliff, the Southern Gateway project will add a third lane in each direction on Highway 67 all the way to Interstate 20. Construction started early this year and is scheduled to finish in late 2021.
