Route 33 commuters should expect slow-moving vehicles and possible lane restrictions on Thursday, according to PennDOT.
The work was originally scheduled for Wednesday, but equipment issues forced the postponement.
Crews from PPL Electric Utilities will be working from 9 a.m. to 5 p.m. between the Route 512 (Wind Gap) and Belfast exits in Bushkill and Plainfield townships.
There may also be rolling traffic stoppages, PennDOT says.
Motorists are asked to use caution when driving through the area.
