Mann Avenue Transit Structure Replacement - Transit Connectivity (Rail and Bus)

completed

Closed

Design and Construction: Mann Avenue bridge is an existing Bus Transitway structure to be converted for Light Rail purposes. Upon evaluation of the existing structure it was determine that there was extensive corrosion in both the east and west abutments of the bridge. Given the age (58 years) and the expected useful life to support the LRT project post revenue service, a review was completed and 3 options were considered, namely; installation of cathodic protection in all the abutment of piles; reinforce the foundation footings; or build a new concrete box-girder bridge. Staff have recommended to build a new concrete box-girder bridge. This option is the least disruption to the light rail schedule, has minimal impact on traffic and utilities with known design parameters (75 years) that will ensure that the new light rail system would have no lifecycle issues during the 30 year maintenance period. Additional work includes 40-foot diesel bus acquisition to support future bus detour/backups for use as may be needed in connection with future LRT-related activities in on or around the area, as well as other related works if/where possible, which may include but not necessarily be limited to connections between pedestrian/cycling locations and transit system locations. These works are intended to further the City’s ability to advance safer community active transportation / transit priorities and are consistent with Council’s strategic direction.
