Project to add additional lane on I-270 starts Monday night

ST. LOUIS (KMOV) – Crews on Monday night will begin lane closures on one of the St. Louis-area’s busiest interstates.

The closures are the beginning of MoDOT's plan to make room for a fifth lane on northbound I-270 between I-44 and Manchester.

Officials say the closures will start at 7 p.m. and run through 5 a.m. every night during the work week as crews start paving and restriping the roadway.

MoDOT says there will be times  during the summer when the portion of highway will be completely shut down for 10- to 15-minute periods while crews blast rock.

But MoDOT officials said they will have to make every lane narrower in order to make room for the additional lane, which has brought up concerns for safety.

The agency promises drivers will experience much shorter delays once the project is complete.

MoDOT plans to eventually add another lane to southbound I-270 between Dougherty Ferry and I-44 next year.

The complete project is expected to take two years.
