Upgrades at busy highway intersections improve safety for drivers, cyclists and pedestrians, improve access to the highway and local roads.
This may include extra turning lanes or traffic lights at intersections, and improved local roads so local residents don't have to use the highway for short trips.
Buses serving various communities along the highway also benefit from an improved road network.
Widened road sections allow for safer pick up and set down of passengers without blocking through traffic.
In some areas, the highway, or local roads, may be widened to improve bus access.
