The provincial government says it's moving to cut delays for GO Transit passengers on buses that use Highway 401 west of Toronto.

The province says bus bypass shoulders will be added to segments of the highway to improve service and reliability for GO buses during peak commuting periods.

By the end of next month, Highway 401 eastbound between Regional Road 25 in Milton and the interchange with Highway 407 interchange will have the new bypass shoulder segments.

They will remain in place until the upcoming Highway 401 expansion occurs, which includes the construction of high occupancy vehicle lanes in both directions.
