DART warns riders that there will be delays this weekend on the Blue, Red, and Orange lines due to scheduled maintenance.

Starting at 10 p.m. Friday, April 24, the track between the Pearl/Arts District Station and SMU/Mockingbird will be reduced to 1 track until 3 a.m. Monday, April 27.

They’ll work on the other track between those 2 stations the weekend of May 8-10, same hours.

The Red and Blue line trains will share a track.

Green Line service will not be affected, and Orange Line service will operate via the Green Line, providing service between Lawnview and DFW Airport stations.

DART says crews will upgrade the fire alarm systems in the tunnels, enhance platform lighting, clean the platforms, and perform repair projects throughout the tunnels during the scheduled closures. Additionally, crews will update and re-tension the overhead catenary system to improve the safety, reliability, and speed of travel into and out of the Cityplace/Uptown Station tunnels.

“We understand how important it is for our passengers to reach their destinations on time,” said Trey Walker, DART interim chief development officer. “While suspending operations for maintenance is disruptive, these planned improvements are vital to ensuring a safer and more reliable experience for our customers.

Once completed, passengers can expect a faster and more efficient trip through Cityplace/Uptown Station. The re-tensioned and upgraded OCS will improve connectivity for trains coming into and out of the tunnel, while the improved lighting and fire alarm system will provide upgraded safety.
