U.S. 20/Idaho 75, Timmerman Rest Area

Project Facts

Key Number: 9618
Project Number: NH-2340(106)

The Idaho Transportation Department (ITD) proposes to upgrade the Timmerman Rest Area to better serve the growing number of travelers using U.S. 20 and Idaho 75. Improvements include expanding the parking area and replacing restroom facilities. Construction is currently programmed for 2010.

Project Backgound

The Timmerman Rest Area is located adjacent to two major state highways - U.S. 20 and Idaho 75. U.S. 20 is a two-lane east-west highway and Idaho 75 is a two-lane north-south highway that is the primary access to the Wood River Valley and Sun Valley area. The existing rest area site currently has five designated parking stalls for car/RV/truck with additional parking available along the internal roadway.

The existing site has two full accesses - one on U.S. 20 and one on Idaho 75. The rest area has heavy usage during peak travel periods. The U.S. 20 corridor currently has Average Daily Traffic (ADT) count of 2,100 with approximately 18 percent using the rest area. The Idaho 75 corridor has an ADT of 4,900 with approximately nine percent using the facility.

The project concept was truncated for a savings of about $1.8 million from original design. Savings will be used for additional road projects.

Project Description

The Timmerman Rest Area improvements are designed to accommodate growth over the next 20 years. The U.S. 20 and Idaho 75 corridors are expected to see a 49 percent and 47 percent growth in traffic, respectively.

At the current funding level, the following improvements are scheduled:

Safety Enhancements

ADA accessible parking, ramps and rest room facilities will be included.

Parking Enhancements

Addition parking will be provided for 54 cars and 10 trucks.
Better separation of trucks and cars in the parking facility.

Building and Site Enhancements

Expanded facilities will include 10 rest room stalls with accommodation for family usage.
Improved site drainage to address runoff and improve the water quality of the adjacent stream.
