The Missouri Department of Transportation is scheduled to close a second lane on the westbound Poplar Street Bridge starting at 8 p.m. Friday, to allow for resurfacing work.
In addition, the ramp from Illinois 3 to the westbound PSB will be closed. Drivers in Sauget who want to go westbound will need to make a U-turn at Barack Obama Avenue to get onto westbound I-64, MoDOT said.
In the section in Illinois where the westbound PSB is split, one right lane is set to be closed on both the northern and southern sections of the bridge. Once the bridges join across the Mississippi River, the two right lanes will be closed on the bridge.
The two right lanes on the bridge are expected to be closed for about a month; crews will then shift work to the two left lanes for a month, MoDOT said. During the work to construct the new driving surface, drivers should be aware of shifting traffic.

The ramp from the westbound PSB to eastbound I-44 is scheduled to reopen in mid-May, shortly before the ramp to southbound I-55 closes for a month for reconstruction.
Although the bridge will remain open through the construction, drivers may want to consider using alternate routes between Illinois and St. Louis, MoDOT said. The new Stan Musial Veterans Memorial Bridge, the Eads and the Martin Luther King bridge are all options during the work on the Poplar Street Bridge.
However, the Martin Luther King bridge is expected to close from July 6 through Nov. 25 for deck replacement and structural steel repairs.
All lanes on the westbound PSB and the ramp from Illinois Route 3 to the westbound PSB are expected to reopen by early July, MoDOT said.
