Ada County Highway District

Swan Falls (Western Heritage Byway) Shoulder Widening, Poen Road to north of Initial Point Road

General Description:

The Ada County Highway District, (ACHD), will be constructing shoulder improvements on a section of Swan Falls Road (Western Heritage Byway) south of Kuna starting in March 2015. The project will begin at Poen Road and extend to about 4,600 feet north of Initial Point Road.

The project includes four-foot paved shoulders on each side of the road, where little or no shoulder currently exists. The new shoulders will create space and improve safety for cyclists and pedestrians, and provide an area for vehicle pull-offs. Construction is anticipated to start March 2015 and be complete by Summer 2015.

About the Western Heritage Historic Byway

The Western Heritage Historic Byway (WHHB) spans more than 30 miles, beginning on Idaho 69 at the Interstate 84 Meridian Road interchange, proceeding south through Kuna, then turning south on Swan Falls Road to Swan Falls Dam.

The WHHB Corridor Management Plan indicates that the lack of shoulders along the Swan Falls Road portion of the Byway is a major deterrent to bicycle and pedestrian use.

In September 2005, the U.S. Department of Transportation and Federal Highway Administration designated it a National Scenic Byway. The WHHB is one of six byways in Idaho to receive this recognition.
For more information on the Western Heritage Historic Byway is available.
