ACTC PS&E: Expected Construction Impacts
Continuous Single-Lane Tube Closures
• Posey Tube: two-year continuous single lane closure
• Webster Tube: 8-month continuous single lane closure
• The two closures overlap by 5 months.
Intermittent Full Tube Closures
• Posey: 23 nighttime closures and 8 full weekend closures spread over two years • Webster Tube: 10 nighttime closures over six months (no full weekends) PS&E = Plans, Specifications, and Estimates 5
City Concerns re Long-Term Single-Lane Closures
Severe impacts on Alameda community:
• Bus riders. Longer waits and much longer rides on all lines serving Alameda.
• Drivers. Major peak hour congestion at all Alameda
gateways.
• Business community. 380+ businesses in West
Alameda who rely on visitors and employees from
outside Alameda.
Alameda seniors catching the 51A from Mastick Senior Center City Actions to Address Concerns
City approach:
1. Proposing solutions to minimize daytime Tube lane closures
2. Informing and engaging community stakeholders
7 City actions spring/summer 2024 :
• Multiple meetings with ACTC, Caltrans, AC Transit, OakDOT • Transportation Commission, City-AC Transit ILC
• Inform & engage community stakeholders
• Letter to Caltrans supporting project with conditions of approval • ACTC meetings: Programs & Projects Committee (PPC), full Commission
1. Seeking Solutions to Minimize Tube Closures
• Developed construction strategies:
o Posey Tube – Reduce lane closures
o Webster Tube – Eliminate daytime single-lane closures and construct with full Tube closures at night (requires extended hours)
• Submitted comments & markups on PS&E, offering alternatives • Exploring ways to incentivize shorter closures through procurement process • Brought construction and contracting concepts to workshops with ACTC and Caltrans engineers
8 City Proposal Highlights
9 Posey Tube
• Constraint: Construction of large
column and retaining wall requires
lane closure.
• Proposal: Construct more components
simultaneously to reduce months
needed for lane closures.
Webster Tube
• Constraint: Need protection for workers
during construction.
• Proposal: Construct with full closures at
nighttime, and place precast curbs so
both lanes can open safely during the
day.
2. Engaging Community Stakeholders
• Met with business, nonprofit, and community leaders
• Shared project benefits as well as anticipated closures • Will continue to advocate for early community engagement and greater transparency throughout the project
