Planned service disruptions

Getting ready for the 33 miles of Link extensions coming over the next few years involves a lot more than just construction on the projects themselves. It also means making sure that our existing operations are in top condition as we prepare to expand our transit system across the region.

As with any system that begins to age, the vehicles, tracks and facilities require maintenance so that our system can continue operating in a safe and reliable manner. This means that passengers will need to prepare for intermittent periods of less frequent service and replacement bus service when available.
