Lehigh Valley road conditions are continuing to deteriorate Friday night, prompting the area’s transit agency to suspend bus service.

LANTA, in a news release, said it would stop picking up passengers on its bus routes as of 8 p.m., though buses would continue dropping off passengers until reaching the next major transit center, or the end of the route. LANTA’s van service will do its last pickups at 8 p.m. as well.

With snow, sleet and even some freezing rain expected to continue through the night, LANTA’s bus and van services will also have a delayed start of 5 a.m. Saturday.

Slick roads are leading to several crashes around the region Friday evening.

One crash was reported with people trapped inside a vehicle on Route 22 westbound near the Route 309 interchange in South Whitehall Township just after 6 p.m., according to emergency radio dispatches. Another vehicle was reported to have gone off the road on Route 22 westbound through “Cemetery Curve” in Easton.

Earlier, a two-vehicle crash was reported on Nazareth Pike (Route 191) at the Route 22 interchange in Bethlehem Township, according to the Northampton County Emergency Alerts Facebook page.
