ST. LOUIS - The Missouri Department of Transportation has extended the closure of the I-70 express lanes downtown to complete needed construction on the Missouri I-70 interchange for the New Mississippi River Bridge project.
This work, scheduled for later this year, was accelerated to let crews take advantage of the current express lane closure. By extending the current maintenance closure, MoDOT can reduce the overall amount of time the express lanes were anticipated to be closed for the Missouri Interchange project.
The contractor for the Missouri I-70 interchange has up to another 45 days they could close the express lanes for construction. By accelerating the work, that additional closure has been reduced to just over two weeks.
The existing long term lanes closures on eastbound I-64 (between Jefferson and the Poplar Street Bridge) and eastbound I-70 (between Madison and Broadway) will reopen by November 1. This will give traffic heading into Illinois through downtown a little extra roadway space, during the extension. The ramp from 11st Street to eastbound I-70 will also open before November 1.
MoDOT will also close two lanes on westbound I-70 between Cass and Madison October 22-24 at 8 p.m. for construction on the Missouri I-70 interchange. The lanes will reopen by 5 a.m. the following morning. When lanes reopen at 5 a.m. October 25, traffic on westbound I-70 between Cass and Madison will temporarily be on three 11-foot lanes. All work is weather permitting.
In addition, the ramp from westbound I-70 to Madison will close at 8 p.m. October 24 for 45 days. Crews will reconstruct the ramp in its new location for the Missouri I-70 interchange. The work and Madison ramp closure on October 24 will be rescheduled around any Cardinals' post season home games.
