With 15 girders and 245 precast panels in place at Merced Avenue Grade Separation, crews are now focused on delivering the remaining aspects of the superstructure. Each abutment diaphragm has been cast with concrete and crews are now completing the remaining falsework and formwork needed before deck reinforcement can be installed. When complete, the Merced Avenue Grade Separation will be more than 509-feet long, 43-feet wide, and will take traffic over SR 43, BNSF, and future high-speed rail lines.

At our most southern portion of Construction Package 4, crews have installed all 15 girders needed for the superstructure of the Merced Avenue Grade Separation. Each girder spans more than 177 feet long and weighs more than 220,000 lbs. The girders were manufactured by Confab out of their Lathrop Plant and are some of the longest girders the company has ever done in California. Confab has also provided pre-cast concrete girders for other high-speed rail structures including the San Joaquin River Viaduct and Pergola in Construction Package 1. When complete, the Merced Avenue Grade Separation will be more than 509 feet long, 43 feet wide, and will take traffic over SR 43, BNSF, and future high-speed rail lines.
