Background

Summit Avenue Bridge spans over Ayd Mill Road and the Canadian Pacific Railroad.  The bridge and approach roadways will be reconstructed in 2019 and 2020.

The new bridge is scheduled to reopen by October 1, 2020.

The first bridge at this location was built in 1897 to span over the Short Line Railroad.  Most of the existing bridge structure was constructed with the development of Ayd Mill Road in 1962.

Ayd Mill Road

  • For work zone safety, equipment and contractor access, Ayd Mill Road will be restricted to one northbound lane and one southbound lane during bridge work.  Ayd Mill Road will be closed and detoured for short durations during critical work activities, such as bridge demolition and setting beams. Traffic delays can be expected.
  • The recently proposed project to add bike and pedestrian infrastructure on Ayd Mill Road does not change the design and construction of the new Summit Avenue Bridge. 
  • As a part of the Ayd Mill Road project, Public Works is reviewing access and accessibility at all existing intersections along Ayd Mill Road.
