The Pennsylvania Department of Transportation announced Monday that core boring operations will take place next week on Route 413 (Pine Street) as part of advance engineering activities for upcoming improvements to U.S. 1 in Middletown Township and Langhorne and Langhorne Manor boroughs, in Lower Bucks County.

Motorists are advised of the following travel restriction:

• Monday, November 7, through Friday, November 11, from 9:00 AM to 3:00 PM, Route 413 (Pine Street) will be reduced to a single lane with flaggers between Flowers Avenue and Woods Drive in Middletown Township and Langhorne Borough.

Drivers are advised to allow extra time when traveling through the work area. All scheduled activities are weather dependent.

The core borings are being done under the third phase (Section RC3) of the U.S. 1 Improvement Program to reconstruct the highway between Penndel/Business U.S. 1 and Corn Crib Lane. Section RC3 is currently in preliminary engineering with construction bids tentatively expected to open in late 2026.

PennDOT is reconstructing and widening almost three miles of U.S. 1, improving the interchanges, and constructing several new bridges — including new structures over the Neshaminy Creek and over rail lines near the Penndel exit— under the first two contracts (RC1, RC2) to rebuild, widen and improve U.S. 1 in Bucks County.

Section RC1 improvements between Old Lincoln Highway and the Pennsylvania Turnpike in Bensalem Township will be completed this fall. Section RC2 improvements from the Turnpike to north of the Penndel/Business U.S. 1 Interchange in Middletown Township are under construction through late 2026.
