Post 1964 Signage History Post 1964 Signage History

In 1970, Chapter 1473 defined Route 271 as “Route 101 near Cummings to Route 101 near the Humboldt-Mendocino county line.” This is a former segment of Route 101 that has been replaced by freeway. The known constructed segments are as follows; there is no cosignage between the segments:

  1. From US 101 in Cummings to Route 1 in Leggett near the Route 1/US 101 junction
  2. From US 101 about 1000 feet north of the Combs Road interchange (about 2 miles south of Piercy) to US 101 in Cooks Valley passing through Piercy and Andersonia

According to Scott Parker (SParker) at AAroads, Route 271 is an "odd duck", intended to be a scenic alternative to US 101, which in the '60's and the '70's was being reconstructed as a limited-access facility generally uphill from the original route that for the most part followed a series of canyons or narrow valleys containing redwood groves. Route 271 was signed in two segments once the US 101 freeway was in place; it was intended that once a freeway segment from Leggett north to Smithe Grove State Park was constructed, Route 271 would be signed over the original highway, connecting those separate segments. Environmental concerns have since halted any freeway development along that stretch of US 101, hence the "split" route on Route 271; the southern section traverses the redwood-filled valley between Cummings and Leggett, while the northern serves Smithe Grove. If/when completed, Route 271 was intended to function exactly like Route 254 (Avenue of the Giants) further north, as a scenic US 101 alternative.

Status Status

In June 2017, the CTC approved for future consideration of funding a project that replaces the McCoy Creek Bridge (No. 10-0036) on Route 271 (01-Men-271, PM 17.70/18.00), in Mendocino County. The project will be funded from State Highway Operation and Protection Program (SHOPP) funds and is programmed in the 2016 SHOPP for an estimated $9.8 million Construction (capital and support) and Right of Way (capital and support). Construction is tentatively scheduled to begin in Fiscal Year 2018-19. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 SHOPP. A copy of the MND has been provided to Commission staff. The project will result in less than significant impacts to the environment after mitigation. The following resource area may be impacted by the project: biological resources. Avoidance and minimization measures will reduce any potential effects on the environment. These measures include, but are not limited to, a revegetation plan will be prepared for the project, Environmentally Sensitive Areas will be designated on construction plans, water drainage from the bridge deck will be channeled via scupper onto rock slope protection, and the work window for demolition of the existing bridge will be from September 15 to October 31 to protect hibernating bat colonies. As a result, an MND was completed for this project.
