PITTSBURGH (KDKA) — Pittsburgh Public Works crews are preparing for snow and icy road conditions that could affect the area until Tuesday.

Mayor Peduto’s office announced Sunday a Level 1 Snow Alert.

Crews have been monitoring road surfaces that are more likely to freeze due to wet snow and high winds.

Approximately 34 vehicles will be out from Sunday evening until 6 a.m. Monday morning. The vehicles will then continue to monitor the roads through Tuesday morning.

The high winds caused more problems, knocking down trees and wires.

The winds knocked down several trees on the T tracks in Beechview. The trees brough down the overhead line that powers the system. Crews worked overnight to clear the trees and debris and repair the damaged lines.

The Port Authority says commuters should allow for extra travel time on the Red Line Monday morning. The service may not be restored before the morning commute, meaning rail shuttles will be operating. Shuttles will operate between Overbrook and Potomac stations, and bus shuttles will run between the Potomac and South Hills Junction stations.

All Red Line riders should anticipate delays.
