A Yukon bridge project will address erosion issues and repair cracks.
The Yukon City Council has approved paying $97,716.81 to Brewer Construction Oklahoma for repairs to the south abutment of the Richland Road Bridge over the North Canadian River.
The project, recommended by Yukon city engineer Robbie Williams, is 0.80 miles north of State Highway 66 on Richland Road.
City of Yukon bridges are inspected annual or bi-annually.
Recent annual inspections of the Richland Road Bridge have noted advances in the erosion of the south embankment and cracking of the south abutment concrete piles, Williams told Yukon City Manager Tammy Kretchmar in a Feb. 15th memo.
“These cracks are likely caused or exacerbated by the advances in the erosion of the south embankment,” Williams explained. “Re-grading of the south embankment and repairs to the south abutment piles are necessary for the stability and longevity of the bridge.”
The Richland Road Bridge is 150 feet long with three spans of prestressed double tee beams (50 feet each), a concrete deck and concrete traffic rails.
WORK TO BE DONE
In the Richland Road Bridge project over the North Canadian River, Brewer Construction crews will:
- Repair cracks in the south abutment concrete piles with epoxy injections and seal coat exposed faces of the concrete piles with CIM 1000 waterproofing to prevent future water intrusion should new cracks appear in the future.
- Re-grade the south embankment to a stable slope with riprap to protect the embankment and adjacent riverbank surfaces both upstream and downstream of the bridge.
- Remove accumulated debris/drift from the channel at the south pier.
The bridge will remain open to traffic during construction, only closing temporarily when needed for public safety.
In a related item, the council approved a change order totaling $31,279.68 for the Richland Road Bridge project to provide the epoxy injections and waterproofing of the concrete abutment.
This second change order increases Brewer Construction’s 2020 concrete and asphalt paving, drainage, water and sewer contract to $1,314.805.73.
The original contract did not have unit price bid items for the epoxy injections and waterproofing, Brewer Construction manager Kevin Brewer explained.
