Frequently Asked Questions
Interstate 10: Prince Road to 29th Street
- Will traffic in neighborhoods
around Interstate 10 increase during construction?
Traffic that typically uses I-10 is directed to the
frontage roads and major streets through a comprehensive
sign program and public information campaign. The use
of neighborhood streets as alternate routes is discouraged.
“Local traffic only” barricades and signs
are in place.
- Has the Arizona Department of
Transportation (ADOT) been working with the City of
Tucson to prepare for this construction project?
ADOT officials are coordinating with city officials
to prepare for the construction’s impact on traffic
and the Downtown Río Nuevo project.
- Will any streets be closed during
the bridge replacement work? Traffic on major
crossroads such as Grant Road, Speedway Boulevard, St.
Mary’s Road, Congress Street and 22nd Street will
be maintained during construction. However, motorists
should anticipate weekend and nighttime closures during
bridge demolition and construction. Turning movements
at crossroads will be maintained. The Clark Street bridge
is closed until further notice in order to move the
bridge 100 feet to the north of the existing bridge
at the request of the City of Tucson for the Rio Nuevo
circulation plan. The 18th Street pedestrian bridge
is closed during construction.

24 hours a day, 7 days a week? Some work is
occuring at night and during weekends.

the annual Tucson Gem, Mineral & Fossil Showcase?
People visiting vendors and businesses along
I-10 will have full access to the Tucson Convention
Center and the frontage roads.
- What is the posted speed limit
on the frontage roads during construction? The
speed limit on the frontage roads remains at 45 mph
and 40 mph.
- Will the stop signs and yield
signs on the frontage roads be removed? The

the I-10 exit ramp closures. After the construction
is completed and the exit ramps reopen, the signs will
be reinstalled.
- Will the traffic signals along the frontage roads be timed? ADOT will make every effort to optimize traffic flow on the frontage roads.
