New pedestrian bridge now open over I-17 just north of Happy Valley Road.
ADOT installed the 160-ton, 600-foot long bridge over two nights in June next to the Central Arizona Project (CAP) canal.

This might sound cliché, but ADOT really is getting rid of the old to make room for the new… It’s happening right now on the San Carlos Apache reservation as ADOT crews construct a new bridge to replace the US 70 Gila River Bridge at Bylas.
The bridge crossing the Gila River outside Florence has quite a few distinctions in its history.

Northbound I-17 bridge at Munds Park
Last week we received a blog comment requesting an update on the I-17 bridges that span over Pinewood Boulevard in Munds Park. We thought it was a great suggestion and figured a blog post was in order!
Interstate 10 in Arizona
The new year officially is here, but before we dive into 2012 we’re going to take a quick look back. ADOT’s Public Information/Media Relations team came up with a great list of the state’s major transportation accomplishments from 2011 and we thought we’d share it here on the blog!
