Anticipate a detour, beginning late next week, on the Route 209 bridge over the Lehigh River at Lehighton in Carbon County.
The next phase of construction to rehabilitate the structurally deficient Thomas J. McCall Memorial Bridge will begin Friday, June 6.
It spans the river, Lehigh Canal and Norfolk Southern rail line in Franklin Township, Lehighton and Weissport boroughs.
Southbound lanes of the bridge will be closed, with southbound traffic detoured on Canal and Bridge streets, reports the Pennsylvania Department of Transportation.
Route 209 will be open northbound, with a single traffic lane.
Also on June 6, Bridge Street temporarily will be converted to a one-way road southbound and a temporary traffic signal will be placed at the intersection of Bridge Street and209.
The new phase of construction is estimated to be completed in September.
Updates will be provided whenever traffic patterns change on area roadways.
The bridge project is scheduled to be complete in May 2015.
