Sundt Moves Ahead On $600M ADOT I-10 Project Since work began on June 25, 2025, on the Arizona Department of CEG CORRESPONDENT Transportation’s (ADOT) $600 million Interstate 10 between Kino Country Club Road Project southeast of downtown Tucson, crews from Sundt Construction and Jacobs have engaged in median embankment, abutment construction and utility relocation operations. The initiative’s goal is to reduce delays and enhance safety. “ADOT initiated the project in this rapidly growing part of Tucson to address traffic capacity and congestion, improve safety, increase traffic flow,” said Garin Groff, an ADOT spokesperson, “and improve two traffic interchanges Kino Parkway and at Country Club Road. The new freeway and interchange configurations will also promote safety with auxiliary lanes that will allow for additional merging space.” Sundt expects to complete work sometime in 2028. The largest highway construction project in southern Arizona history is reconstructing and widening a 3-mi. section of I-10 between Kino Parkway and Alvernon Way from two lanes to three lanes in each direction, with auxiliary lanes; reconstructing the interchange at Kino Parkway; constructing a new interchange Country Club Road to provide access for traffic that uses the interchange at Palo Verde Road to allow for safer traffic movements to and from I-10; removing the existing interchange Palo Verde Road; and constructing a new westbound on-ramp at the Alvernon Way interchange and an I-10 undercrossing to connect the North and South Kino Sports Complex.

Reconfiguration Ahead Work includes reconfiguring the nonstandard ramp configuration at the two interchanges to construct more traditional diamond interchanges. Also, ADOT is closing an existing interchange at Palo Verde Road due to its proximity to another interchange at Alvernon Way. A new interchange at Country Club Road will promote safety and a better flow of traffic by providing more space from the Alvernon interchange to the east.
The largest highway construction project in southern Arizona history is reconstructing and widening a 3-mi. section of I-10 between Kino Parkway and Alvernon Way from two lanes to three lanes in each direction, with auxiliary lanes.
I-10 is the sole east-west interstate serving Tucson, a rapidly growing metro area of 1 million, and the rest of southern Arizona. Average daily traffic counts range from about 95,000 near the west end of the project at Kino Parkway to 75,000 at the east end near Alvernon Road. The project will feature a relatively new type of interchange for southern Arizona: the diverging diamond. “ADOT chose this design for Kino Parkway and I-10 over a traditional diamond interchange (DDI) based on traffic patterns, traffic volumes and safety,” Groff said. “This
will be only the second diverging diamond interchange in southern Arizona, following the completion of the I10/Houghton Road DDI that opened 10 miles to the east in 2021.” According to ADOT, “the project is the first to result from a study completed in 2020 that recommended how to best improve mobility along a roughly 10-mi. stretch of I-10 from Interstate 19 to Kolb Road.” Jacobs, the lead design firm, is designing the project. see SUNDT page 6
