Work on the single-lane roundabout at Market Street, Pennsylvania Avenue, and Water Street in the city of Warren, Warren County is expected to move into the third stage of work on Wednesday.

Stage 3 will include the roundabout being opened to eastbound traffic on Pennsylvania Avenue as well as for westbound traffic on Pennsylvania Avenue coming from Market Street.

The intersection will be closed to all traffic on Pennsylvania Avenue westbound and Market Street northbound. The following detours will be in place:

— Market Street northbound – Pennsylvania Avenue eastbound to Glade Bridge to Route 6 to Ludlow Street to Pennsylvania Ave to Laurel Street to Route 62 to Market Street.

— Pennsylvania Avenue westbound – Pennsylvania Avenue eastbound to Glade Bridge to Route 6 to Ludlow Street to Pennsylvania Avenue

— The intersection will be closed to all truck traffic. Trucks and other large vehicles must follow the posted detour and will not be able to turn or turnaround in the work area.

— Access to all businesses in that area will be maintained throughout the construction process. Stage 3 is expected to take approximately four weeks to complete.

In Stage 4 of the project, the roundabout will be open to all traffic with flaggers and short-term lane restrictions as needed.
