There will be one more night of delays on Interstate 83 in the area of the North Sherman Street bridge as a contractor installs bridge beams.

Traffic stoppages are estimated to last up to 15 minutes at a time, according to the state Department of Transportation.

Traffic stoppages can be expected between 9 p.m. and 6 a.m. and state police will be assisting with traffic control, PennDOT said

Work on beam installation at the bridge between Springettsbury and Spring Garden townships started Monday and was expected to be finished Thursday.

The beam installation is part of an $8.9 million project to replace the bridge, which is expected to be reopened in December.
