State College Public Works crews on Tuesday will make repairs to a traffic signal loop wire detector at Westerly Parkway and South Atherton Street.

The work will require crews to reduce northbound traffic to a single lane between 9 a.m. and 12:30 p.m., and drivers should expect delays.

Delays for drivers and pedestrians also can be expected Tuesday and Wednesday while crews remove a tree in the 400 block of West College Avenue.

That work will take place between 7 a.m. and 3 p.m. both days and will require a closure of the left lane of travel.

Questions should be directed to Public Works at 234-7135 or 234-7140.
