SR 105 - North River and Smith Creek Bridge Replacements - Complete November 2014

This project replaced the existing SR 105, North River and Smith Creek bridges with two new bridge spans built of concrete girders. The new 36-foot-wide structures consist of two 12-foot-wide lanes and six-foot-wide shoulders. It also straighten a curved section of the highway.

The old bridges were constructed in 1959 of timber trestles. They were aging and too narrow to accommodate the types or number of vehicles that need to cross them today. They also did not meet current federal seismic, flood, or structural standards.

The new bridges were competed in November 2014. They help improve safety and increase mobility on SR 105 along Willapa Bay between Raymond and Tokeland.
