PennDOT District 8 today announced that on Friday, July 25, at 9 p.m., weather permitting, construction crews will close the Lowther Street ramp to I-83 South in order to finish construction of the new ramp in Lemoyne Borough.
PennDOT advises motorists that flaggers will maintain traffic flow through the intersection of 10th Street and Lowther Street for the duration of the detour.
The weekend detour will be lifted as soon as construction of the ramp tie-in to Lowther Street is complete, as early as Saturday night but no later than 6 a.m. Monday, July 28. Until then, Lowther Street traffic to I-83 South will continue east on Lowther Street to I-83 North, exit at 13th Street, to I-83 South.
Once the detour is lifted, the new ramp from Lowther Street to I-83 South will be opened to traffic and traffic movements between the existing ramp and Shoreham Road will no longer be permitted.
PennDOT has also set message boards announcing that July 31, weather permitting, the northbound I-83 Exit 42 ramp to Third Street in Lemoyne is scheduled to close permanently. Once this exit is closed, northbound I-83 motorists headed to Lemoyne must use the Exit 41-B and eastbound Route 581 motorists headed to Lemoyne must use Exit 6-C.
This work is part of the $22.1 million contract that was awarded to J.D. Eckman Inc., of Atglen, Chester County, which will make several safety and congestion mitigation improvements to the I-83 interchange with Route 581 and the adjacent ramps.
The entire project is scheduled for completion in the summer of 2015.
