CIP32046 - West Beaver Creek Boulevard Bridge Rehabilitation Design

The West Beaver Creek Boulevard Bridge within the Town of Avon was constructed in 1979 and spans the Eagle River in Eagle County, Colorado. The bridge is situated within the town’s Right‐Of‐Way and carries an ADT of 3,203 as of 2017. This rehabilitation project is proposed to address all items identified in the Maintenance Activity Summary of the most recent CDOT Structure Inspection and Inventory Report to improve structure rating from Fair to Good. The design should meet all relevant building codes, regulations, and industry standards. The bridge is located between Avon Elementary School and the intersection of US6 and West Beaver Creek Boulevard. The bridge is 90’ in length and has a curb-to-curb width of 28’ with an overall width of 36.5’ including an attached recreation path and separating parapet wall to the east.  The CDOT Structure Inspection and Inventory Report by  Benesch dated 06/14/2022 gave the bridge a sufficiency rating of 72.6.
The Town of Avon is seeking a design team to develop the construction documents to address the following issues with the existing facility.

1. Patch potholes and spalls in deck and wearing surface.
2. Patch spalls and scaling in rail parapets
3. Remove thin bonded epoxy and chip overlay.
4. Scarify concrete deck surface.
5. Place polyester polymer concrete overlay
6. Remove debris from the bearing seats.
7. Patch spall in top of east end of south abutment (A1) and under bearing at Girder D
8. Seal gap between the tops of wingwalls and ends of deck.
9. Replace failed seals at north and south ends of deck.
10. Address deficiencies in light pole bases.
11. Evaluate existing guardrail structure and design a replacement/upgrade that meets ADA/PROWAG guidelines.
