Route 339 Project Continues Next Week in Columbia and Luzerne Counties


Montoursville, PA – The three-year reconstruction and road widening project of Route 339 between Route 2017 (Smith Hollow Road) in Mifflin Township, Columbia County and Route 3015 (Broad Street) in Nescopeck Borough, Luzerne County will continue next week.

The week of Monday, September 26, the contractor, Mitchell Knorr Contracting, will continue excavation for the reconstruction of the northbound lane of Route 339. Contractor will also complete work on previously started storm drainage systems and structure work over two unnamed tributaries. Work will be completed during daylight hours.

Traffic Impacts

A long-term lane restriction will be implemented on Route 339 southbound between Smith Hollow Road and Broad Street. The following detour route will be implemented, with signs and message boards leading up to and throughout the detour:

  • Route 339 southbound traffic will take Broad Street in Nescopeck to Route 93 north towards Berwick, to Route 11 south to Market Street in South Centre Township, to the Market Street bridge, back to Route 339 in Mifflinville.
  • Route 339 northbound traffic will be able to travel on the northbound lane from Mifflinville to Nescopeck.
  • Traffic will no longer be permitted to enter 339 from Smith Hollow Road due to Smith Hollow Road being closed.

Motorists should be alert, expect delays in traffic and drive with caution.
