Highway construction projects going on around the valley:
-- Loop 101: Two separate widening projects. One from I-17 to Pima Rd/Princess Dr in north Scottsdale. The other from US 60 (Superstition Freeway) to Loop 202 (Santan Freeway). At least one new general purpose lane in each direction.
-- I-17: Bridge replacements at Pinnacle Peak Rd and Happy Valley Rd. The Happy Valley interchange is being redone to remove the roundabouts and replace with a DDI. When it opens, this should be Arizona's first full DDI to open. The other DDIs under construction on the Loop 202 (South Mountain Freeway) are only going to be half interchanges (at 17th Ave and Desert Foothills Pkwy).
-- I-10: Other than the new interchange with Loop 202, a new interchange at Fairway Dr (or El Mirage Rd alignment).
-- Loop 202: The South Mountain Freeway seems to be progressing well. A video link shows most of the alignment. (Note, the video is real estate related. It just happens to cover most of the construction zone.)
