Pothole repairs and minor paving could slow traffic in the Route 283 construction project in Dauphin County overnight.
State police will use rolling roadblocks, beginning at midnight, between the west end of the work zone near the Pennsylvania Turnpike and the Route 283 interchange with Vine Street, according to a PennDOT news release.
PennDOT spokesman Greg Penny said the work will start with minor paving on the ramp from southbound Interstate 283 to eastbound Route 283, then continue for pothole repairs on eastbound Route 283, then westbound Route 283.
The final stretch is the ramp from southbound I-283 to eastbound Route 283.
The rolling roadblocks should wrap up around 4 a.m. on Saturday.
At that time, the contractor will close the westbound Route 283 lane for local traffic to pave just east of Vine Street. A detour will direct all westbound traffic approaching the construction zone to take the express lane to the I-283/Turnpike interchange.
Drivers headed to the Airport Connector, Union Street, or Vine Street exits will then be directed back onto eastbound Route 283.
The westbound lane for local traffic should reopen around noon on Saturday.
