A portion of the Regional Transportation District E and H lines in southeast Denver will be shut down Tuesday through Thursday next week for maintenance, but RTD officials said bus shuttles will carry passengers between the Southmoor and Broadway/I-25 stations. Maintenance crews need to grind down “rail-burn” bumps on tracks to help eliminate the 10-mile-per-hour slow zones along the Southeast Corridor,” agency officials announced Wednesday in a news release. RTD riders can catch the bus shuttles at multiple stations:  I-25/Broadway (gate A2); Louisiana/Pearl Station (northbound gate B, southbound gate A); University of Denver (gate B); Colorado (northbound gate E, southbound gate C); Yale (gate A); Southmoor (gate A). RTD’s website also has a trip planner to help riders find alternate routes.
