Campus Construction and Testing Notices

Major Impacts - Summer 2026

As minor construction and light-rail vehicle testing continues, watch for the following impacts this summer:

Overnight Light-Rail Vehicle (LRV) Testing

• Scheduled Dates (subject to change): 
  • Testing is expected to continue through August, on select nights. Testing will not occur when there are major events on campus.
    • Wednesday, 8/19 from 10 p.m. until 12 a.m. - Single direction, single movement of LRV tow truck through campus with LRV (no campus road closures are expected beyond the brief stoppages at intersections)
• Testing Hours: Testing will occur on select nights from 10 p.m. until 6 a.m. the following day from the WMATA College Park Metrorail station to UMGC. 
• Impacts:
  • Temporary holds of up to 15 minutes will occur along the Purple Line tracks and all cross streets as the LRV travels back and forth across campus. Crews will be deployed ahead of the police-escorted LRVs to briefly block cross streets and crosswalks to ensure driver and pedestrian safety. See map for details.
  • The following roads will be closed from 10 p.m. until 6 a.m. the next morning each night of testing:
    1. Campus Drive between Preinkert Drive (near Anne Arundel Hall) and Union Drive (near the Benjamin Building)
    2. Connector road between Lot C1 (near Turner Hall) and Lot L (Lot C1 exit)
    3. Rossborough Lane between Yale Avenue and Diamondback Drive
  • Some crosswalks will be closed and others will experience periodic holds to allow the LRV to pass safely; follow pedestrian detour signage and flagger direction. See map for details.
  • Expect traffic delays as the LRV passes through and use caution when traveling through the area.
  • Emergency vehicles will have unfettered access at all times.
  • Shuttle-UM service may experience delays or detours. Check the Transit App for alerts and real-time arrival information.
