Union City is also served by a network of high-capacity streets, with four exits on Interstate 880 (Nimitz Freeway), express lanes will open on Interstate 880 Freeway by 2020. Highway 238 also serves the city (Mission Boulevard).Union City is planning the East-West Connector Project, a 3.0-mile roadway project that would provide improved east access between I-880 on the west and Mission Boulevard on the east in south Alameda County between the cities of Fremont and Union City. The proposed project would achieve this objective by widening roadways (Decoto Road and Paseo Padre Parkway), constructing a new roadway segment, from Paseo Padre Parkway to Mission Boulevard).The current project is under design phase and will break ground in the future.
