Silverton Road Bridge Replacement

Marion County has received funding for the replacement of the Silverton Road Bridge over the Little Pudding River. The county analyzed three options for the alignment of the replacement bridge. The first option was to close Silverton Road and construct the new bridge centered on the existing alignment. This would cause the least impact to properties on both sides of the bridge and would cost the least, but it would have required closing Silverton Road between June and November.  The other options considered require widening to the north or south side of the existing bridge.  These options would greatly impact adjacent properties, would cost approximately $1,500,000 more to construct, and would require two construction seasons to complete.  However, either of the second two options would allow Silverton Road to remain open during construction.. 

After public meetings at Marion County Public Works and meeting with the City of Silverton City Council, the county has selected Option 1 as the preferred option, which will require closing Silverton Road during the summer and fall of 2021.  The county hopes to lessen delays along the detour route of Howell Prairie and Hazelgreen Roads, by installing temporary signals at two of the intersections along the route.
