A design of a third roundabout at the Rifle I-70 interchange could be finished this summer, after City Council awarded a nearly $310,000 contract for the work to Colorado River Engineering of Rifle.
City Engineer Rick Barth told the council at its Jan. 16 meeting that three bids were received for the project. SGM (formerly Schmueser Gordon Meyer) and Sopris Engineers were the other bidders, with Colorado River Engineering the lowest.
Funds for the design work come from a Garfield County Federal Mineral Lease District grant and city matching money, Barth noted.
"They'll be finishing the engineering that took place when the city built the first two roundabouts and we'll update the traffic counts," he said.
The city built the two existing roundabouts in fall 2008 as part of a $4.1 million bond issue approved by voters in 2003 for a variety of street improvement projects. However, there wasn't enough money at the time to build the third roundabout.
Barth also said the work could be expanded to include landscaping details to follow an earlier concept plan developed as part of the Gateway project. It could also include aesthetic improvements to the bridge over the Colorado River on Colorado Highway 13.
Once the design is in hand, it will be submitted to transportation agencies for approval, then the city can seek grants to do the actual work, Barth said.
