A pair of traffic lights have been put up along Route 209 in Towamensing Township in advance of bridge maintenance work.

The lights, which are covered, have been placed in the area of the 209 bridge over Bull Run, near the area of Stagecoach Road.Sean Brown, safety press officer for the Pennsylvania Department of Transportation District 5, said the lights will be used as temporary signals to control traffic during construction once the road is reduced to one lane of traffic.The signals will be turned on around the end of April, said Brown, who added the project will take about eight weeks to complete.Brown said the work will be to reconstruct part of an arch culvert that is 8 feet long and 24 feet wide. Crews will also replace the deck, and install new guide rail.
