Bridge Removal & Replacement - Over Blackmud Creek at 111 Street and at 30 Avenue SW

About the Project

The City identified the 111 Street Bridge over Blackmud Creek as having reached the end of its service life. The bridge was removed and the crossing reclaimed.

The 30 Avenue Bridge over Blackmud Creek has also reached the end of its service life and required replacement. The approved concept plan for 30 Avenue SW was for a 4 lane configuration; however, due to traffic volumes, only two lanes were constructed at this time.

Where We Are Today

This project began in October 2012 and was completed in fall 2013.

The scope of work for the 111 Street over Blackmud Creek bridge, included:

• Removal of the existing 111 Street bridge – a 3-span structure with a timber substructure and a precast concrete superstructure.
• Reclamation of the bridge site with an appropriate landscape design.
• Closure of the road right of way.

The scope of work for the 30 Avenue Bridge over Blackmud Creek, included:

• Construction of a new 42m long single span bridge on the approved new 30 Avenue SW alignment.
• Construction of a 3m wide Shared Use Path on and under the new 30 Avenue bridge.
• Construction of a 7m wide wildlife corridor under the new 30 Avenue bridge.
• Removal of the existing 30 Avenue bridge – a 3 span timber trestle.
• Reclamation of the bridge removal and reconstruction sites with an appropriate landscape design.

Timeline

Construction began with earthwork in October 2012. Bridge construction and completion of the 30 Avenue Bridge over Blackmud Creek was carried out during the 2013 construction season.
