The westbound express lane in the Route 283 reconstruction project in Dauphin County will be closed for a period tonight so damaged signs can be repaired.

The closure will happen around midnight until 5 a.m., PennDOT said. The signs were damaged along the express lane last week.

The local traffic lane will remain open and available for westbound traffic. Traffic is light overnight, so major disruptions aren't anticipated.

Here is how the work zone works:

The westbound "local" lane is for access to and from the Vine Street, Union Street and airport connector interchanges. Drivers will still be able to continue to I-283 and Harrisburg area destinations. Drivers headed to I-283 are encouraged to use this lane for "local traffic."

The westbound "express" lane will have no access to the ramps for the Vine Street, Union Street and airport connector interchanges. Drivers headed to the turnpike or Eisenhower Boulevard should use the "express lane."

Last week, PennDOT and police announced there were 15 crashes since the construction zone traffic changes went into effect March 26. They included the death of one pedestrian.

Speeding through the construction zone - which now has a 55 mph limit - is a concern, said Greg Penny, PennDOT spokesman. Other issues have been traffic line visibility and potholes, compounded by inclement weather, he said.

PennDOT is continuing to examine whether improvements can be made in the signs approaching the work zone for westbound traffic, Penny said.
