Nightly work on I-270, from Manchester to I-44, begins April 16
MoDOT will close various lanes on Interstate 270 in this section during night time hours of 7 p.m. to 5 a.m. on weekdays in April and early May.
These 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 I-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, it should increase the average speed to 50 mph during the morning commute and reduce the delay to three minutes. Construction of northbound widening work is scheduled to occur this year. The southbound work begins in 2013.
