The Regional Transportation District will replace about 1,600 feet of overhead electrical wires at Denver Union Station to ensure safe and reliable operations on the E and W light rail lines, according to the transit authority.

Service to and from Union Station on the E and W lines will be interrupted beginning at the start of service on April 11 and continuing through the end of service on April 13. Regular service for all lines will resume Tuesday, April 14.

“As part of the Building a Better RTD strategic initiative, we’re investing in proactive maintenance like this to strengthen our system, ensure dependable service, and limit unplanned impacts to our customers,” RTD Deputy CEO Angel Peña said in the news release.

RTD schedules bus shuttles to provide service to customers during planned rail maintenance, unplanned service disruptions or elevator outages. Bus shuttles provide service at or between affected rail stations.

For the E Line, service will be rerouted to the Downtown Loop, instead of Union Station. Trains will detour from 10th-Osage Station to Colfax at Auraria Station and continue to the 16th and 18th street stations at Stout and California. Customers can connect to Union Station using temporary bus shuttle service from 10th-Osage Station or via the 16th Street FreeRide or Free MetroRide.

For the W Line, bus shuttles will replace rail service between Auraria West Station and Union Station, with stops also accommodating transfers to and from the E Line. W Line customers can board shuttle buses at the following locations:

• 10th-Osage Station: bus bridge gate on Osage Street
• Empower Field at Mile High and Auraria West stations: bus bridge sign at 5th and Larimer streets
• Ball Arena-Elitch Gardens Station: bus bridge sign at station (Chopper Circle roundabout)
• Union Station: Gate B22 (underground bus concourse)
