Bicycle, Pedestrian & Trails Committee Agenda Report January 23, 2023 Item 4 SUBJECT: REVIEW OF THE DRAFT CONCEPTUAL PLANS FOR THE I-580 OVERCROSSING IMPROVEMENT PROJECT SUMMARY The I-580 Overcrossing Improvement project consists of bicycle and pedestrian improvements on three overcrossings at I-580. Conceptual design plans were prepared for the overcrossings of I-580/Hopyard Road, I-580/Hacienda Drive and I-580/Santa Rita Road. The preliminary design plans were completed in 2019. An operations analysis was completed to determine if the preliminary design would create excessive delays. This operations analysis did show that several of the preliminary design concepts created vehicle backups through adjacent intersections, which requires minor revisions to the preliminary design. This project is ranked third on the BPMP priority list but fit well into a Highway Safety Improvement Program (HSIP) grant opportunity. The HSIP Cycle 11 grant was awarded to the City on March 6, 2021, for $250,000. In addition to this funding, TDA Article 3 will be used to match the grant funding in the amount of $190,000. Fehr & Peers (F&P) was selected as the design consultant to update the preliminary design plan to a full construction plan set that will incorporate best practices for bike and pedestrian facilities adjacent to Caltrans facilities. The updated preliminary plans are being provided to the BPTC for review and feedback. See Attachment 1. The plans will also need to be reviewed by Caltrans and the City of Dublin. It is expected that the full construction plans will be available for review in the Spring of 2023 and construction possible upon Caltrans approval possibly in the Fall of 2023. RECOMMENDATION It is recommended that the Bicycle, Pedestrian & Trails Committee receive and consider this report, and provide staff with any input deemed suitable.
