Recent Progress
This contract was advertised to bidders on January 16, 2007. Bids were opened on March 14, 2007. The low bid was approximately 10% over the engineer’s estimate. Additional funding was allocated during the 2007 legislative session and the project was awarded to IMCO in April 2007. Work began on June 4, 2007.
Most of the work to date has focused on utility relocation, which in most part is being done by the respective utility companies. Underground and overhead utilities need to be relocated in order to facilitate widening of the roadway. This work is expected to be completed by 12/31/07.
Other work has focused on the construction of the west side of the new bridges at Fourmile and Tenmile Creeks. We cannot remove the old structures and finish these bridges until our next environmental window opens, which is the summer of 2008.

Design Construction Impacts
As there are numerous utilities in this corridor and it is anticipated that visible progress may not be apparent this first year. Most construction activities focused on underground utility installation, overhead utility installation and relocation and bridge construction at Tenmile and Fourmile Creeks.

Environmental Impacts / Compliance
This project will provide storm water detention and treatment ponds. New wetlands will also be constructed to mitigate for impacts during construction.
Environmental permitting for the entire project is complete. Environmental issues and new wetlands discovered in the wetland re-delineation completed in late 2004 have pushed the projected advertisement date out from the originally scheduled April 2005.

Impacts to Traffic
Staged construction will minimize traffic impacts. During construction, one lane of traffic in each direction will be open at all times. Detour routes will be provided when side roads are closed.
Roadway closures will be allowed for limited durations during night time hours. When there are roadway closures signed detours will be provided on county roads.
