Construction on the four-mile segment between Loop 303 and Dysart Road began in March 2012 and was opened in December 2013. Construction of the overpasses at Reems and Litchfield Roads began in summer 2014 and was completed in January 2015. With the completion of those interchanges, this four-mile segment was upgraded to freeway standards. The project stalled from 2015–2019 as Maricopa County saw less growth in this region than expected because of the Great Recession.
