RTD to suspend L Line service for rail repair work on Welton Street

In order to repair a section of rail near 30th and Welton streets, RTD will suspend L Line light rail service for 20 days beginning Monday, July 10, and continuing through the end of service on Sunday, July 30. L Line customers are encouraged to explore Bus Route 43 as an alternative service. 


The project will replace a segment of one of the oldest sections of track on the RTD light rail system and make improvements to the crossings at Downing and 30th Streets.

  • D and H Line trains will continue to operate and serve downtown stations (16th•California, 18th•California, 16th•Stout and 18th•Stout).
  • The 30th•Downing light rail station will remain accessible for Bus Routes 12, 28 and 38.
  • Welton Street will be closed at 30th Street during the work, and there will be a lane shift on 30th Street to accommodate construction of an ADA curb ramp.
  • Southbound Downing Street will be closed at 30th Street; traffic will be detoured to California Street.
  • Work will take place every day of the project schedule. Work hours are Monday-Friday, 7 a.m.-7 p.m. and Saturday-Sunday, 8 a.m.-4 p.m.
  • The work will be loud. RTD’s contractor will remove and replace all track, paving, rail, ties, switches and ballast rock, the rock beneath the rail, from the intersection of 30th and Welton streets through the southern end of 30th•Welton Station.

Normal service will resume on Monday, July 31. Customers are encouraged to use RTD Next Ride web app to plan their trip, view other options and receive Service Alerts.

RTD thanks L Line neighbors and customers for their patience as the agency works to make lives better through connections.

During the months of July and August, RTD will offer zero fares across the entire system as part of the Zero Fare for Better Air initiative. This collaborative, statewide initiative is made possible by the Colorado Energy Office during high ozone summer months.
