Construction on I-270 Widening Project Starts Monday

Various lanes of the interstate from Manchester Road to Interstate 44 will be closed nightly through early May.

Construction on I-270 Widening Project Starts Monday

The released the following update about the Interstate 270 Widening Project.  

The Missouri Department of Transportation will begin construction on the Interstate 270 Widening Project between Manchester Road (Route 100) and Interstate 44 starting Monday.

MoDOT will close various lanes on Interstate 270 in this section from 7 p.m. to 5 a.m. on weekdays in April and early May.

Lane closures are necessary for crews to perform paving and restriping work to prepare for the widening work on the interstate. Because of the restrictions on the roadway and rock bluffs, MoDOT will permanently narrow all lanes on northbound and southbound I-270 to 11 feet (the same width as I-44 during the I-64 reconstruction in 2009 and 2010). Upon completion of the project, this section of roadway will still have full width shoulders in most locations.

Construction for this entire project on I-270 will occur for approximately two years, which includes widening work, roadway construction, work in the rock bluffs and installing soundwalls.

MoDOT will narrow and shift the existing four lanes from Manchester to Interstate 44 in the two-year project, so motorists will have no shoulders in some locations as crews widen the road. There should be some lane closures at night as a part of this work. When construction is completed, travel time through this corridor should decrease during peak hours and reduce the delay. Construction of northbound widening work is scheduled to occur this year. The southbound work begins in 2013.
