As work continues along Interstate 180 on bridges over Loyalsock Creek between exits 21 and 23, traffic patterns are expected to change today.
The contractor is expected to close the right lane and open the left lane in both directions.
Message boards will alert drivers ahead of the work zone of slow-moving or stopped traffic.
Daily traffic queues have been reported at various times of day.
The project remains on schedule to have the barrier removed for Little League Baseball World Series week, and will return to daylight patterns for the epoxy overlay of the bridge decks.
