PCL Civil Constructors, Inc., completed the first CM/GC bridge and lateral bridge slides in the state of Vermont by using accelerated bridge construction (ABC) methods to successfully slide the Northbound and Southbound Interstate-91 bridges into place. The firm’s work will be discussed during a free webinar hosted by the ARTBA Bridge Policy and Promotion Council from 2:30 p.m. to 3:30 p.m. EST on Jan. 26.
The project consisted of removing the existing bridges, sliding the new 136-foot span bridge 50 feet into place, lowering the bridge onto permanent bearings, and all maintenance of traffic to support the closure. PCL slid the I-91 bridges into place in under six and four hours, respectively, with two falsework and jacking system configurations. This method resulted in a safe completion that was delivered ahead of schedule.
The webinar will discuss how PCL provided successful ABC methods to complete the project under critical time constraints for the Vermont Agency of Transportation.
