PennDOT to Close McMillan Road for 65 Days

Starting on Monday, June 20, PennDOT will close McMillan Road at the McLaughlin Run Road intersection between McLaughlin Run Road and Woodlands Circle for 65 calendar days, weather permitting. Construction crews will replace a culvert located on McMillan Road, located just west of Woodlands Circle and will reconstruct the roadway for the roundabout intersection project.

Traffic will be maintained in each direction on McLaughlin Run Road and Lesnett Road as three temporary traffic signals guide motorists through the intersection.  

PennDOT's $4.67 million project will convert the signalized McLaughlin Run Road and McMillan Road/Lesnett Road intersection into a free-flowing, single-lane roundabout. The overall work is expected to conclude in fall 2022.
