Work In Progress: Interstate 10 and SR 143 Ramp Connections

In late April, crews set concrete girders over lanes of Interstate 10 to connect the ramps that will link the highway to State Route 143. Workers are now constructing the bridge deck, which is the part of the bridge vehicles drive on. Crews expect to open the bridge connecting southbound SR 143 to eastbound I-10 in late summer and the high-occupancy vehicle (HOV) ramp connecting SR 143 and I-10 in late 2024.

These girders will form the support for the bridge deck of the ramp connecting southbound SR 143 to eastbound I-10.

Plan Ahead: Long-Term Ramp Closures and Restrictions

As we head into the summer months, several ramps are closed in the I-10 Broadway Curve Improvement Project area. Drivers are encouraged to plan ahead and allow extra time for detours.

Crews closed the eastbound I-10 off-ramp at 32nd Street in March for ramp reconfiguration and they are on track to reopen the ramp in June. Drivers can use the I-10 off-ramp at 40th Street as an alternate route.

Workers closed the eastbound I-10 off-ramp at Baseline Road last week and plan to keep it closed into July. During the closure, continue on eastbound I-10, exit at Elliot Road, turn left onto eastbound Elliot Road to access westbound I-10 and exit at Baseline Road.

Later this year, crews have the following long-term closures planned:

• The westbound I-10 on-ramp at 32nd Street.
• The HOV ramps that connect US 60 and I-10.
• Guadalupe Road between Pointe Parkway and Calle Sahuaro.

Crews closed the eastbound I-10 off-ramp at Baseline Road so they can reconfigure the ramp.

Find Your Lane

The westbound Collector-Distributor (CD) road is scheduled to open in early summer and the eastbound CD road is scheduled to open in late summer.

What are CD roads?

Collector-Distributor roads collect traffic from the I-10 mainline, SR 143 and US 60 and distribute it to crossroads or other highways. They separate through-traffic from local traffic entering and exiting I-10 through the Broadway Curve area. This will reduce the need for vehicles to weave between lanes and help keep traffic flowing on I-10.

How do the CD roads work and how will drivers access common destinations in the Broadway Curve area upon completion of the project?

Depending on your entrance location and destination, CD roads may change your travel route on I-10 between Baseline Road and 40th Street, so we have a webpage dedicated to helping drivers navigate the CD roads once they open: https://i10broadwaycurve.com/findyourlane/.

Once open, drivers on westbound I-10 heading to Phoenix Sky Harbor International Airport will exit westbound I-10 south of Baseline Road and use the westbound CD road, shown here, to access northbound SR 143.

Your Questions Answered Question: Why are there solid white lane lines throughout the project area? Answer: The solid white lane lines indicate a traffic shift. Drivers should remain in the lane while the lines are solid because all lanes are shifting. This is particularly important between 48th Street and Broadway Road because the lines guide drivers around work zones that are between the travel lanes. It is also important to drive 55 mph through the project area because these lane shifts are designed for traffic driving at that speed. The shifts will seem very abrupt at higher speeds.
