St. Louis Work Zones August 17-23

ST. LOUIS – Drivers who use Interstate 270 in St. Louis County should be aware of ramp closures along the corridor this weekend.

Weather permitting, crews will close the ramp from eastbound I-44 to northbound I-270 (Exit 276) Friday, August 18 at 8 p.m. for continuing bridge preventative maintenance. The ramp to southbound I-270 will remain open.

In addition, crews will close the ramp from westbound I-270 to southbound I-170 (Exit 26A) for continuing preventative maintenance. The ramp closes Saturday, August 19 at 5 a.m.

Both ramps reopen Monday, August 21 by 5 a.m.

The detour for the eastbound I-44 to northbound I-270 ramp will be to take southbound I-270 to Route 30 (Gravois/Exit 3). After crossing over the interstate, drives can continue on northbound I-270.

The detour for the westbound I-270 to southbound I-170 ramp closure will be to continue on westbound I-270 and exit at Lindbergh (Exit 25), cross over the interstate and take eastbound I-270 to southbound I-170 (Exit 26A).

Drivers who regularly use the westbound I-270 ramp to northbound Route 367 should look for alternate routes or allow extra time as the department will close the ramp for two months, starting Monday, August 21at 6 a.m. The closure will allow crews to complete the northbound fly-over ramp.
