Northwest of Kingman and just over Coyote Pass, US 93 has an interchange with SR 68 (exit 67). This junction incorporates a large Commercial Vehicle Inspection Station (CVIS), which ADOT calls a Port of Entry (POE), for southbound and eastbound commercial traffic. Highway 68 heads west over the Black Mountains to Davis Dam, Laughlin and Bullhead City (the latter via SR 95), while US 93 continues as a four-lane divided route towards the northwest. Running through the long Detrital Valley, with the Black Mountains to the west and the Cerbat Mountains and then the White Hills to the east, US 93 passes several small settlements in this mostly remote area. As it nears the Nevada state line, it enters the Lake Mead National Recreation Area and climbs over Householder Pass, before crossing into Nevada via the Mike O'Callaghan-Pat Tillman Memorial Bridge over the Black Canyon just downstream of the Colorado River from Hoover Dam.
