The existing Keystone Road Bridge crossing over Hairsine Creek is an 8.4m long structure supported by prestressed concrete girders.  The steel reinforcing within the prestressed girders is showing signs of deterioration necessitating the replacement of the entire structure.

The new bridge will be wider and longer and will accommodate higher stream flows from Hairsine Creek.  Works include some channel widening and armoring.  All environmental approvals are in place and environmental monitoring will be completed by the City of Mission in accordance with Provincial and Federal approvals and regulations.

In order to complete these works safely and efficiently, Keystone Avenue will be closed to traffic from Wolf Street to Dewdney Trunk Road.  Changeable message boards will be in place to notify the public and the detour route will be marked with signage.
