Drivers traveling on State Route 89 at Hell Canyon Bridge (milepost 345) starting tomorrow (March 3) should expect intermittent delays of up to 30 minutes at a time as crews begin placing girders on the new bridge over Hell Canyon. Traffic will be stopped in both directions approaching the project.

Impacts for up to 30 minutes at a time are expected between 10 and 11 a.m. and again from noon and 1 p.m. The installation of the girders will be done by very large cranes, positioned in the bottom of the canyon, that need to be flown over the existing bridge causing the temporary closures.

In addition to the delays tomorrow, crews will again place girders next week, Tuesday through Friday (March 8 through 11) between 10 and 11 a.m. and again from noon to 1 p.m.

ADOT advises drivers to proceed through the work zones with caution, slow down, and be alert for construction equipment and personnel.
