Highway 40 detours map

UPDATED at 8:25 p.m. :  Highway 40 between Hampton Avenue and Forest Park Avenue has closed.

ST. LOUIS  •  This weekend’s closure of Highway 40 will give way to narrower lanes on the stretch of interstate between Vandeventer Avenue and Kingshighway.

The Missouri Department of Transportation is reminding drivers that Highway 40 (Interstate 64) will close at 8 p.m. Friday between Hampton Avenue and Forest Park Avenue to remove the Taylor Avenue and Newstead Avenue bridges over the highway. The section of highway will reopen at 3 a.m. Monday.

MoDOT’s contractor Fred Weber Inc. will restripe the highway, leaving it with three 10-foot-wide lanes in each direction between Kingshighway and Vandeventer. Crews will close one to two of those remaining lanes for nighttime and weekend work.

The Vandeventer ramp to westbound Highway 40 will close this weekend and will remain closed until the fall.

During this weekend’s work, traffic will be diverted around the highway closure. Long term, MoDOT officials urge drivers to consider other routes or telecommuting and flexible work hours.

The state is rebuilding bridges at Taylor, Newstead, Tower Grove and Boyle avenues, and a new interchange at Tower Grove/Boyle.

The Washington University Medical Center and BJC Healthcare are shouldering a portion of the $17.9 million price tag.

The highway construction is expected to extend into mid-2014.
