The bridge, located about 35 miles east of Boise, was recently inspected and is deemed unsafe for full sized vehicles due to the movement of a bridge pier.  The pier was damaged following the floods in 1997 and has been monitored since then.  In a recent inspection a steel truss support has weakened and the agency is concerned with its structural strength.


The bridge is primarily used by recreationists to access dispersed undeveloped campsites on either side of the river.  Access to those sites on the north side of the river will be from Highway 21 via Forest Road 327 (Granite Creek), and on the south side from the Middle Fork Boise River via Forest Road 376 (near Alexander Flat).

The bridge will have the restriction indefinitely.  Funding requests have been submitted to the Intermountain Regional Foresters office for further investigation of the foundation pier and to evaluate repair options.
