BRIDGE CONTRACT AWARDED 1-12-15 LMS
The contract for construction of the Rattlesnake Bridge has been awarded to TrueNorth Steel of Missoula, Montana.
There was only one bid submitted for the project which had been advertised for three consecutive weeks. The bid opening took place at the January 12 meeting of the Lemhi County Commissioners. The amount of the bid was $500,654.
Dan Sharp of Northwest Engineering was on hand to immediately review the bid specification standards and after clarifying a few details with TrueNorth Steel Area Manager Cory Claussen, who was also in attendance, Sharp stated the bid met the specification requirements. The commissioners voted to accept the bid and then signed the required county commitment. Pending a legal review the project will proceed. The bid was agreeably lower than expected.
Now that the contract has been awarded the permitting application process will commence.
The 300,000 pound bridge will be 190 feet long and delivery date is May 22, 2015.
Northwest Engineering has been in charge of preliminary design, research, abutment needs and all structural details related to the building of a new bridge across the Salmon River approximately 16 miles south of Salmon and adjacent to US Highway 93. The structure will replace the old bridge which has been closed for several months due to being deemed unsafe by the state.
After the contract was awarded Sharp went on to describe the logistics of putting the bridge in place. Bridge girders of 90 feet and 100 feet long will be assembled on the east side of the river then hoisted into place by a Manitowoc Crane large enough to reach across to the river’s west bank. He said the crane will be hauled in on 17 trucks. The counterweights to balance the crane’s tremendous reach will be hauled in a separate load. When the crane is in operation it will be necessary to limit Highway 93 traffic to a single lane.
Abutment construction, crane costs and all other related expenses will be in addition to the amount of the bridge structure itself.
