This summer, Pittsburgh Regional Transit (PRT) is beginning major renovation and repair work on the Red Line of the light rail transit system. PRT expects the work to begin in the middle of June and end in early September. Riders using the Arlington, Poplar and Mt. Lebanon stations will face some temporary changes in their commute. 

Alternatives include using the Washington Junction Station in Bethel Park taking the Blue Line, or boarding the 37 Castle Shannon bus shuttle, which stops at each Red Line T station between Mt. Lebanon and Station Square. This will run every 30 minutes during weekends and during peak times on weekdays.

A short rail shuttle will run between Potomac Station in Dormont and Overbrook Junction in Castle Shannon. From mid-June to mid-July, shuttles will run every 30 minutes. From mid-July to the end of August, shuttles run every 15 minutes during peak and 30 minutes off peak.

In addition to the Red Line work, all three lines in May and June will be single-tracking—sharing the same line for both northbound and southbound cars—between the Willow Avenue and St. Anne stations. Expect several minutes of delay during this time. 

In June and July, the Red Short Rail shuttle will be single-tracking between Poplar and Mt. Lebanon stations. The rail shuttle will come every 30 minutes instead of every 15 minutes.   

In June through August, the Red Line between Dormont Junction and Potomac Station will be fully closed. Riders will need to use the 37 Castle Shannon bus shuttle or other shuttle routes instead. 

Other light rail projects are being completed through 2027, which will impact service, but the direct closures of the Mt. Lebanon stations are expected to be complete by September.
