The City of Phoenix is replacing the bridge over the Grand Canal on 24th Street. Major cross streets are McDowell Road to the south and Thomas Road to the north.
Replacing a bridge is a highly choreographed event. This particular project has 106 specific tasks or milestones. The construction activity takes place above and below ground and above and below the waterline. Crews will mostly work 14-hour days. During the dry out period, work will continue around the clock on a seven day per week schedule.
The bridge replacement has 106 specific tasks or milestones broken into four phases:
Phase 1 – West side/south and north ends before dry up
Phase 2 – East side/south and north ends before dry up
Phase 3 – Bridge demolition and reconstruction during dry up (24/7 schedule) –
This is in January when there will be a two week full closure of the area and mandatory detours. (complete!)
Phase 4 – Installing the approach slabs under the west side of 24th Street before moving to the east side of 24th Street to finish those approach slabs and remaining street construction. (Bridge reopened July 2020, minor work remaining!)
The existing bridge was installed more than 75 years ago and is reaching the end of its useful life. The bridge was reopened on February 17, 2020 as scheduled. Project was anticipated to be completed in the Spring of 2020, but is now expected to be completed by the Summer of 2020.
