MoDOT is telling drivers, some temporary pain will be worth the permanent traffic relief.
The plan is to add another lane to southbound Interstate 270 between Manchester Road and Interstate 44.
Starting March 18 and continuing through April, crews will begin closing all lanes twice a day for 15 minutes at a time, while they blast to make room for the new lane.
This is similar to work that was done to add a lane on northbound 270 last summer.
District Engineer Ed Hassinger tells KTRS News, that addition has subtracted time from drivers' morning commutes, "The traffic volumes have increased and the speeds on northbound 270 have gone up anywhere from 10-15 miles an hour during the worst time, during rush hour."
The new lane on southboun 270 should be open by December.
