I-10 Construction Project

I-10 freeway in Tucson will be under construction for several years to widen the roadway. Demolition of I-10 bridges will also require temporary closure of some local roads.

Between Prince Road and 29th Street:

I-10 is opened for through traffic but all on- and off-ramps are closed
Local traffic and freeway access traffic will use the frontage road

Bridge demolition (I-10 underpasses):
Roads beneath I-10 will be closed while portions of the bridges are removed. The schedule for this work is given below. Each I-10 underpass will be closed until Monday at 6 a.m.

Sat., July 14 at 12:01 a.m. - Grant Road underpass
