MoDOT To Close I-170 July 8-11 For Delmar Bridge Construction

MoDOT will close Interstate 170 near the Delmar Boulevard Bridge starting at 7 p.m. Friday, July 8 to construct portions of the new bridge.

All lanes of the interstate will reopen by 5 a.m. Monday, July 11. Traffic on the interstate will be detoured up the ramps at Delmar and back onto the interstate while the roadway is closed.

Traffic on the interstate will not be able to access Delmar Boulevard during the closure, nor will traffic on Delmar be able to access I-170 in either direction. Detours are marked. Traffic levels on both the interstate and the detour routes are expected to be high; drivers are encouraged to avoid the area if possible or use other routes.

While the interstate is closed, crews will be setting girders and installing portions of the driving surface.

This work is part of a $2.1 million dollar project to replace the Delmar Boulevard Bridge. Although the bridge was already scheduled for replacement this year, MoDOT closed it April 25, after an inspection showed the bridge had become unsafe for public use. Construction has been underway since May 20. The bridge is scheduled to reopen by September 1.
