Work starts Monday, Jan. 11, with line painting on Interstate 78 between Exit 57 at Lehigh Street and Exit 60 at Route 309 in Allentown. A PennDOT contractor will restrict lanes in both directions from 7 a.m. to noon that day.
The most extensive project begins Tuesday, Jan. 12, on MacArthur Road in Whitehall Township between Center Street and Chestnut Street. A PennDOT contractor will conduct construction work including signal upgrades, intersection improvements, and Americans with Disabilities Act curb ramps through Oct. 30, 2026. Shoulder restrictions will run from 7 a.m. to 5 p.m. daily, with lane restrictions from 9 a.m. to 3 p.m.

Affected areas include Trexlertown Road in Upper Macungie Township, Hamilton Boulevard between Weiler’s Road and Route 222, Route 29 between the Berks County line and Cedar Crest Boulevard, and Spinnerstown Road, Dillingersville Road, and Zionsville Road in Lower Milford Township. Additional crack sealing work will take place on State Avenue and Lehigh Street in Emmaus and Allentown through Jan. 16.
