Interstate 79 traffic will drop to a single lane in both directions from Thursday through late March in the area of the Route 422 interchange in Butler County, PennDOT said.

The left-hand lane will close in both directions about 7 a.m. Thursday so crews can continue building temporary crossovers through the interstate's median in Muddy Creek. Contractors will use the crossovers to divert traffic around planned work to replace the interstate's two bridges over Route 422.

The work is part of a $14 million project to make improvements in the area, used by about 25,000 vehicles a day, on average. The project will be completed in fall 2014.
