In Construction Package 4, the year kicked off with crews completing the installation of 15 pre-cast girders to form the superstructure of the McCombs Road Grade Separation. Work was completed over the four nights. Crews are now working on other superstructure elements and are preparing to place concrete for the abutment diaphragms. When the abutment diaphragms are formed, crews will begin installing 360 pre-cast concrete deck panels on top of the superstructure. When complete, the McCombs Road Grade Separation will be 415-feet long and will take traffic over, State Route 43, existing BNSF rail lines, and future high-speed rail lines.
