Crews in Bethlehem and Salisbury Township are repairing breaks that have shut off water to dozens of homes as frigid temperatures grip the region.

In Bethlehem, crews worked most of the day on an 8-inch break in the 2600 block of East Boulevard. The break has caused 20 homes to be affected with water shut off, Edward Boscola, the city’s Department of Water and Sewer Resources director, told lehighvalleylive.com.

Work was completed by 3 p.m. Monday and service was restored, he said. Eight of the 20 families are being asked to boil water for the next three days, Boscola said.

That stretch of East Boulevard remains closed for road restoration. Boscola expected repairs to be completed by early Monday evening.

In Salisbury Township, police Sgt. Bryan S. Losagio told lehighvalleylive.com crews are working on a smaller break along a bustling stretch of East Emmaus Avenue — between Potomac and Dauphin streets.

Traffic is shut down in both directions; however, school buses and local motorists are being allowed to pass through, he said.

Crews began work around noon Monday and are expected to finish repairs by 6 p.m., Losagio said. An unspecified amount of homeowners in the vicinity of the break have since had their water turned off.

“Residents in this area will be out of water until it’s repaired,” Losagio said.

Another water main break is being worked on in Lower Saucon Township, WFMZ-69 News reports. Residents in Phillipsburg had their water service shut off this past weekend as the result of a break along Pickford Avenue.

Dangerously cold wind chills in the single digits once again impacted the Lehigh Valley Monday morning, with the Poconos seeing colder values reaching near 15 degrees below zero.

Air temperatures Monday morning were hovering around 15 degrees in the Lehigh Valley, combining with steady to gusty northwest winds to produce dangerous wind chills, according to the National Weather Service.

Daytime highs Monday were only expected to reach the upper 20s to low 30s, with some spots possibly touching the freezing mark depending on sunshine.

The region is forecast to experience continued below-normal temperatures throughout the week, with highs generally remaining in the 20s to low 30s through Friday.
