It's the park over the highway, not the Poplar Street Bridge ramps, that will cause detours next weekend in downtown St. Louis.
The Missouri Department of Transportation will close all lanes of Interstate 44 from Broadway to the Poplar Street Bridge, known as the depressed lanes, as well as all lanes of the Eads Bridge, at 8 p.m. June 6. Lanes will reopen by 5 a.m. June 9.
Traffic on eastbound Interstate 44 will detour up and over the closed portions of northbound Memorial to Third Street near the Edward Jones Dome, then return to Interstate 44 after the Martin Luther King Bridge.
Westbound Interstate 44 will detour down Broadway. Traffic bound for Interstate 55 will use Spruce to exit; traffic bound for eastbound Interstate 64 will take Gratiot to the Sixth Street ramp.
The weekend's work is part of the ongoing CityArchRiver Park Over the Highway project to allow access from downtown St. Louis to the Arch grounds. View the ongoing construction by webcam at http://oxblue.com/open/modot/cityarchriver.
This week, workers closed westbound ramps carrying I-44 and I-55 traffic, and Memorial Drive traffic, off the Poplar Street Bridge. Those ramps will be closed for a year-long project to widen the I-44/I-55 ramp to two lanes.
