The community was named for a relative of William Wimer, who edited a newspaper in Grants Pass in 1886–87. Grants Pass is about 17 miles (27 km) southwest of Wimer. William Wimer was also said to have helped establish a post office in Wimer, which remained open until 1909. Simon E. Simpkins was the first postmaster.[7]
Wimer Bridge is a covered bridge that crosses Evans Creek in Wimer. It replaced a 1927 version of the bridge that collapsed into the creek in 2003. In 2008, with the help of federal funds and local labor, the bridge was replaced with a look-alike using stronger materials. The one-way bridge, still 17 feet (5.2 m) wide, as was the original, has a load limit of 10 tons.[8] This version of the bridge opened to traffic in February 2008.[9]
