Updated February 2, 2017: RTD has announced that train testing on the G Line has ceased until the grade crossings on the University of Colorado A Line are resolved. Once testing resumes, G Line trains may be on the tracks for testing every day between the hours of 8 a.m. to 6 p.m. During testing, train horns will be sounding and traffic delays can be expected. To avoid traffic delays, the following roadways do not have G Line crossings and will not be affected by the testing: Kipling Parkway, Wadsworth Bypass, Ralston Road, Sheridan Blvd. This safety testing is a Public Utilities Commission and Federal Railroad Administration requirement.

Traffic signal timing changes required by the PUC are being made. During this time, traffic signals may operate in flash as a fail safe. This is normal and Traffic Engineering staff will work with DTC to ensure that these signals continue to operate as designed.

Power lines along the G Line (Gold Line) are turned on. These wires hold 25,000 volts of electricity and can be extremely dangerous. RTD asks everyone to please stay away from the tracks and the wires, and never try to touch or throw anything at them. Trespassing in active work zones is illegal and can be dangerous.
