Midland Saves Big on Bridges
When Midland County was faced with a growing inventory of deteriorating bridges and a shrinking budget, cost effective and long lasting solutions were crucial.
Luckily, the Valmont® Bridge System was up for the challenge.
Project Timeline
- July 2018 – OHM Advisors release a single project for bid. The bid requires materials for both bridges to be delivered by spring 2019.
- August 2018 – Valmont Bridge System is awarded the project and begins design and shop drawing process.
- September 2018 – Design and drawings are reviews and approved by OHM Advisors
- September 2018– Valmont Structures begin fabrication of the U-BEAMs (Steel Press-Brake-Formed Tub Girders)
- December 2018– Fabrication and galvanization of all 12 U-BEAMs is complete
- January 2019 – Girders are shipped to ADL Systems, a precast concrete producer in Lansing, MI
- April 2018/2019 – Precast concrete deck is manufactured. ADL completes the process and stockpiles 12 bridge girder units until Midland County is ready for installation
- May 2019 – An extremely wet spring and summer prevents GRS abutments for the Orr Road Bridge, an impediment that likely would have created additional costs if using a contractor and the traditional method
- August 2019 – County takes delivery of 6 Valmont U-BEAMs for installation atop the county-installed GRS abutments for the Orr Road Bridge.
By the end of August, all installation was completed. The bridge deck joints were then filled with a durable, high-strength polymer concrete product known as Transpo T-17. The bridge opened to traffic in October after the guardrail had been installed by the county.
