Grade Separation: North Milliken Avenue Project
San Bernardino Associated Governments and the City of Ontario are working to construct a bridge (also known as a grade separation) over Milliken Avenue in the city of Ontario. The bridge will carry the east/west Union Pacific Railroad (UPRR) tracks over Milliken Avenue.
The 1.5-mile long project will construct a railroad bridge over Milliken Avenue at the existing Union Pacific Railroad train crossing, located between Guasti Road and Airport Drive. The project will eliminate the need for motorists to wait for trains to cross, and enhance safety by separating vehicle and pedestrian traffic from train traffic.
Upcoming Traffic Info:
As part of The North Milliken Grade Separation Project, the city of Ontario and San Bernardino Associated Governments will require the closure of northbound Milliken Avenue and westbound Airport Drive at the intersection of these two streets to allow for the removal of asphalt pavement and replacing it with concrete. The closure runs from Friday, April 26 at 9pm to Monday, April 29 at 5am. (See Press Release)
Only a few full closures of the intersection are anticipated during construction, mainly at night for construction of the bridge structure. A detour route will be provided in these instances.
Construction is expected to begin in early 2011 and last approximately two years. The total cost of the project is $63 million. Funding sources include state andlocal funds, like Measure I, the half-cent sales tax for transportation improvements in San Bernardino County, UPRR, Southern California Edisonand City of Ontario transportation funds.
