Bus on shoulder training

C-TRAN has used Bus on Shoulder lanes since they were first implemented in Clark County in 2017. The concept allows transit vehicles to use the shoulder of a given corridor to bypass traffic during times of heavy congestion. It creates faster travel times for buses and more reliable transit service for our region’s commuters.

(Bus on Shoulder: Frequently Asked Questions)

There are limitations:

  • For a bus to use the shoulder, the overall speed of traffic must be less than 35 mph.
  • While using the shoulder, buses are only allowed to go up to 15 mph faster than other traffic, to a maximum speed of 35 mph.
  • Priority for shoulder use is always given to emergency vehicles, stalls or breakdowns.

Bus-only shoulder lanes are currently in use or planned on three freeway corridors in the region: State Route 14, Interstate 5 and Interstate 205.
