|CLOSURE SOONER THAN EXPECTED|
BRIDGE CLOSED 7-14-14 LMS
The elderly Rattlesnake Creek Bridge, which spans the Salmon River 16 miles south of Salmon, has been closed due to safety concerns. The bridge is on the west side of highway 93 and supplies access to Twin Peaks Ranch and to the Twin Peaks Mine beyond the ranch as well as to some ranch sites on the river’s west side.
Lemhi County Road and Bridge representatives Jay Davis, Dan Davis and Kim Thomas made the bridge closure announcement at the July 14 meeting of the Lemhi County Commissioners.
Jay Davis is the county’s Road Access Specialist and has been working on gathering all possible options to bridge replacement or alternate road access options.
In May the board commissioned Northwest Engineering Services to do a bridge study. That study will include detailed summaries on bridge and road alternatives. The study in progress is to help determine the financial feasibility of even having a bridge in that location as opposed to the cost of building a north or south bound road.
Options being considered in light of the recent emergency bridge closure include reopening the old road on the west side of the river from the Rattlesnake Bridge north through Salmon’s original golf course at Lake Creek. From there the road intersects with the Williams Lake access road and continues to the Shoup Bridge. The other possibility is opening the west side road from Rattlesnake Bridge south to Iron Creek Bridge.
If it is determined the bridge should be either totally replaced or fixed, an access road in one direction or the other will still be required during the construction period.
Engineers and county crews were scheduled to start removing planks on the bridge’s deck later that afternoon to determine if the structure can be made safe for temporary use, how long the interim fix would take and how much it would cost.
