Bridge File 76077


Project Name: Bridge Replacement of Bridge File 76077
Location: Picture Butte, AB
Description: Replacement of the 3 span, 3 x 6.1 m type PG girder bridge on a treated timber substructure with a 3 span, 10m – 12m – 10m type SL-510 on a steel substructure.


Roseke Engineering helped Lethbridge County with the replacement of this three span bridge, including an expedited design phase to ensure that the work was eligible for funding from the provincial government.

The existing bridge was nearing the end of its service life with several rotten caps and piles, and the south pier had sunk about 3 inches.  The new bridge was placed slightly to the north of the existing bridge and the abutments were slightly staggered.

During the preliminary engineering phase, investigation determined that the south canal bank had been repeatedly repaired near the east side of the bridge.  It consisted of poor, wet material that consistently sloughed in.  During the bridge replacement project, the piles were driven past this poor material, and some of it was removed to ensure the long term integrity on the south abutment.

As with all irrigation canal bridge projects, the irrigation district had to be consulted and reviewed the design plans prior to tender.

We are excited that we had to opportunity to help the County with this bridge project and the delivery of their bridge program.

Our bridge division has performed hundreds of bridge projects and can ensure they run smoothly.
