The Oregon Department of Transportation (ODOT) worked with Yaquina River Construction to find a solution to cross Simpson Creek at Oregon Highway US 20 in Eddyville, Oregon.

It was necessary to find a structure that would allow for a quick installation in order to minimize road closure time. In addition to considering the community impact, it was necessary to consider the impact to the environment because it would be spanning an existing stream.

“This bridge was a very important component to our project,” said Joe Squire, Project Manager with ODOT. “Not only was this an environmentally sensitive crossing over Simpson Creek with habitat for Coho and Chinook Salmon, but we also had to consider summer-time traffic on this major route to the coastal communities. Minimal disruptions during this peak tourist season demanded that a quick installation was paramount.”

A CON/SPAN Bridge System was chosen because it offered clear spans from 12 to 60 feet with small footprints that minimize intrusion into natural areas. CON/SPAN also offered the needed quick installation because of the set-in-place construction as well as lower initial costs, precast quality, a long service life, an attractive appearance and extensive technical support.

The CON/SPAN bridge met all of ODOT’s manufacturing specifications and in less than 30 days from breaking ground, Elk City Road was reopen to traffic. The project was an overall success with top of the line design, technical support, timely delivery, speedy assembly and a high quality product.
