Adams Avenue Grade Separation

The Adams Avenue Grade Separation is nearly complete. This spring, crews completed the deck of the structure and concrete barrier rail. Crews have begun grading embankments and will begin placing base coarse and paving the roadway in the coming weeks. When complete, the Adams Avenue Grade Separation will span 357 feet long, 40 feet wide and will take traffic over BNSF and future high-speed rail lines.

At Adams Avenue in Fresno County, crews recently installed 16 concrete pre-cast girders to form the superstructure of the Adams Avenue Grade Separation. Now, crews are gearing up to set pre-cast concrete panels to form the deck of the structure while ironworkers tie rebar for the diaphragms, the supporting portion of a bridge that goes between each girder to help prevent girders from rotating and to help distribute vertical load distribution.

At Adams Avenue in Fresno County, crews continue to work on the substructure for the future grade separation. Crews are nearly complete with the five concrete footings, two abutment walls and columns needed for the substructure. Superstructure work for the bridge will begin in 2022. When complete, the Adams Avenue Grade Separation will be 357 feet long, more than 40 feet wide and will take traffic over the BNSF and future high-speed rail lines.

In November, a new construction site broke ground in Fresno County at the Adams Avenue overcrossing. Crews have completed the original grade preparations including closing and demolishing the roadway and are now hauling-in dirt for preliminary work on the slopes of the structure.
