13) 98th Ave./I-880 -- This $36 million project to rebuild the interchange began construction in early ’96 and will be completed in spring 1998. A pedestrian overcrossing linking communities on both sides of the freeway was recently opened. Construction is being managed by the Alameda Co. Transportation Authority (ACTA) with project oversight by Caltrans.

14) Hegenberger Rd./I-880 -- Also managed by ACTA, this $28 million project to rebuild the interchange began construction in 1996 and will finish in summer 1998.

15) Hwy. 84 Realignment – This project to realign Hwy. 84 through Fremont and Union City is in the environmental review stage with final approval scheduled in December 1998. Caltrans has chosen the Historic Parkway as the preferred alternative. A highway agreement with the cities is required. The cost estimate is $66 million. A public hearing was held in February 1997. Construction is scheduled to begin in 2001.

16) I-238 @ I-880 – In late summer ’98, Caltrans will begin a $3.3 million project to widen I-238 between the Nimitz Freeway and E.14^th Street. This project will provide a third lane in the eastbound direction of I-238, eliminating the bottleneck at the 880 merge. Construction will be completed by the end of 1999.

All of the above projects on I-880 consist of some of the following elements:

1) Widening the freeway from six to eight lanes to provide a continuous carpool lane in both directions from Mission Blvd. to its current terminus at Whipple Road. The carpool lane will open in summer 1998.

2) Widening/strengthening (seismic retrofit) freeway overpasses.

3) Reconfiguring interchange on/off ramps.

4) Constructing soundwalls.

5) Landscaping the interchanges and freeway.

All cost estimates are total costs that include design, right-of-way, utilities, environmental mitigation and construction. The carpool lane will not be available until all of the interchanges are rebuilt and the extra lane put into operation.
