The project encompassed more than 9 miles of roadway alignment and includes 26 bridges and three toll plazas.
As the primary water source for the Contra Costa Water District, the Los Vaqueros Dam measures 1,000 feet across and 192 feet high. During construction, project personnel suggested a value engineering concept that considered the creation of rip rap from on-site oversized rock from the excavation. This resulted in more than 50,000 cubic yards of rip rap generated on-site.
The rehabilitation of eight segments of catenary lines from New Rochelle to Sunnyside Yard included installing 1.5 million pounds of miscellaneous and structural steel to support 15 miles of registered track.

Using an innovative approach, the project team chose to reuse existing ESP steel for the J.T. Deely Unit 2 SCR Retrofit Project instead of opting for demolition. This decision reduced the project construction schedule while minimizing disruption to plant operations.
