ACTC I- 880 /Davis St- Westgate Pkwy Interchange 2 May 16, 201 I Portions of the 1- 880 /Davis Street - Westgate Parkway Interchange work are a part of the Westgate Parkway Extension project, which is included in the Alameda County Transportation Improvement Authority (ACTIA) Measure B program as Project 18B. The objective of the ACTIA project is to improve traffic operations and reduce congestion on Davis Street by adding a lane of traffic in each direction on Davis Street between the 1 -880 off -ramp and Timothy Drive. The construction of this work is to be coordinated with the 1 -880 HOV Lane project. The original scope of work for Westgate Parkway Extension was to provide north -south access and capacity between Davis Street and Marina Boulevard west of I -880 through a direct connection from Williams Street to Davis Street. Under consideration for traffic operations on Davis Street between the 1 -880 Southbound Off-ramp and Timothy Drive was the requirement to close the Timothy Drive access to Westgate Parkway. However, this proposed alignment was rejected by both the Timothy neighborhood (perceived neighborhood access constraints) and Caltrans (current Caltrans standards for alignment of local streets and off - ramps). The southem portion of Westgate Parkway Extension, which links the Westgate Shopping Center to Williams Street, was completed as Phase 1 (ACTIA Project 18A) of this project. As expected, this connection has provided tremendous traffic relief to the Davis Street entrance to the shopping center. As an alternative to the direct connection of Westgate Parkway to Davis Street, it was decided to add one lane in each direction of travel on Davis Street from the 1 -880 southbound off -ramp to Davis Street - Timothy Drive /Warden Avenue. The lane widening will provide additional capacity to relieve the traffic bottle -neck between the southbound 1 -880 off -ramp and Beecher Street. In addition, a pedestrian bridge was proposed to enhance safety and traffic signal efficiency at the intersection of Davis Street and Timothy Drive /Warden Avenue. Prior to embarking on the design of the pedestrian bridge; however, staff sent out a survey to the residents of the Davis West neighborhood to determine the level of interest in a pedestrian bridge. A total of 98 surveys were sent out. Only 11 residents replied to the survey. An analysis of the results indicated that seven of the residents favored the proposed pedestrian bridge. Four residents did not support the bridge based on the extended travel distance required and pedestrian safety while crossing Timothy Drive to get to the shopping center. This group suggested that the money be moved to other uses in the city. The strongest resistance to the bridge came from residents who live closest to the proposed bridge site. Based upon this feedback it was decided not to proceed with the pedestrian bridge. ACTC, ACTIA, Alameda County (County), the City of Hayward and the City of San Leandro recently completed a study identifying and prioritizing improvements for 1 -880 in central Alameda County. The I- 880/Davis Street - Westgate Parkway Interchange project is one of the projects reviewed in the study. The study preliminarily estimated the design and construction cost for the entire interchange. An a lvsis The 1 -880 I -IOV lane project requires reconstruction of the Davis Street Overcrossing, but does not provide for the improvements to the interchange. The City's desired improvements to the interchange include: lane configuration changes; traffic signals; bridge lighting; and other
