One such change has been the recent downcutting of the river channel adjacent to the pier foundations of the US 101 Elwha River Bridge. In October 2016, Washington State Department of Transportation (WSDOT) did borings which revealed that the pier foundations are bearing on gravel, not bedrock. WSDOT immediately responded by placing riprap around both foundations and is continuing to monitor the situation as they develop long-term alternative solutions. Exhibit A is a list of the proposed WSDOT design alternatives. Since Exhibit A came out WSDOT narrowed the design alternatives to Alternatives 5, 6, and 7. Analysis/Strategic Goals/Pro's Et Con's: Highway 101 is the primary route connecting East and West Jefferson County. This road is vital for providing critical services and for supporting the West Jefferson County economy. Some of the WSDOT alternatives include closing the bridge and rerouting traffic to SR 112/113. SR 112/113 do not provide reliable access and frequently close during winter months due to landslides and downed trees. Extended closure and rerouting of traffic is not a desirable nor practical option. Consequently, staff recommends the Board sign the attached letter supporting Alternative 7. This alternative limits traffic interruption, provides a modern bridge, provides safe passage for pedestrians and bicyclists, and improves safety by correcting the roadway geometry. Fiscal Impact/Cost Benefit Analysis: None. Recommendation: Please sign and mail the attached letters to the Washington State Department of Transportation Olympic Region Manager with a copy to the Communications Manager. Return a copy of the signed letter to Public Works (Attn: Zoe Ann Lamp).

Box 47440 Olympia, WA 98504-7440 RE: US 101 Elwha River Bridge — Design Alternative #7 Dear Mr. Wynands: We appreciate WSDOT's ongoing effort to ensure that US Highway 101 at, the Elwha River Bridge, remains open to traffic. As the primary route connecting East and West Jefferson County US Hwy. 101 is essential to maintaining vital services for our residents and supporting the West Jefferson County economy. We have reviewed the design alternatives and strongly support Alternative 7. This alternative: • Keeps the highway open during the anticipated lengthy construction period. • Provides improved pedestrian and bicyclist passage. • Improves public safety by correcting the roadway geometry. We encourage you to accomplish this project as soon as possible to avoid prolonged interruption of access to our citizens on the West End. Thank you for this opportunity to provide comment on the US 101 Elwha River Bridge proj ect.
