Construction contractors will now begin building the new southbound Houghton Road Bridge over the Union Pacific Railroad after Wednesday's demolition.
Construction will start within the next several days.
There are no traffic restrictions associated with the work, because all of the Houghton Road traffic is sharing lanes on the new northbound Houghton Bridge.
Houghton's improvement project also includes widening, intersection improvement, and landscaping between I-10 and Speedway, conducted over a period of several years.
Here's a time lapse of the final demolition of the bridge from Tucson DOT Project Manager, Austin Wesnitzer.
Early this morning the final girders of the existing Houghton Road Bridge were removed! With this last step complete construction of the new bridge will be able to begin! #TDOT @Tucson_DOT @RTAMobility pic.twitter.com/fyYsGNSuo4
