St. Louis County, Mo (KSDK) -- The Missouri Department of Transportation will begin construction on the Interstate 270 Widening Project between Manchester Road (Route 100) and Interstate 44 starting 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.
During the closure, crews will work on paving and restriping 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).
Construction of northbound widening work is scheduled to occur this year. The southbound work begins in 2013.
Upon completion of the project, this section of roadway will still have full width shoulders in most locations.
Construction will last an estimated two years.
