27th Street and West “O” Street Bridges Over Salt Creek

North 27th Street and West “O” Street Bridges Over Salt Creek

City #540029 (NDOR Project No. LCLC-5231(15) / CN 13247)

The purpose of this project is to preserve the transportation system, improve the reliability of the transportation system, and perpetuate the mobility of the traveling public.

The 27th and Fairfield bridge over Salt Creek was built in the mid 1980's and is in need of rehabilitation. The existing bridge expansion joints are on top of the back wall and have failed, allowing for road salt and water to seep onto the back wall and abutment bearings. The jersey barrier rail is also showing signs of deterioration. The appropriate pedestrian protection on the west side of the bridge needs to be installed. The northeast corner wing on the abutment needs to be re-built to correct overturning and separation from the abutment, and repair the leaning traffic signal pole.

The West “O” Street bridge over Salt Creek was constructed in mid to late 1990's. Currently the existing approach and paving sections are settling at the grade beam. The settling has created a consistent maintenance issue.

Scope of Work

Repairs at the North 27th and Fairfield Bridge consist of:

• Removing the back wall abutments and replacing with turndown, as well as moving the expansion joint onto the grade beam
• Removing and replacing existing grade beams on new piling.
• Replacing the northeast abutment wing
• Removing and replacing the bridge rail and approach paving sections
• Replacing the traffic signals at Fairfield and 27th Streets
• Replacing overhead street lighting on the bridge

Repairs at the West “O” Street Bridge consist of:

• Replacement of grade beams on new piling
• Removing and replacing the approach and paving sections
• Repairing guardrail and pavement adjacent to the project
