Alameda County Congestion Management Agency Reveals Plans for $74 million I-880 Improvement Project.

By Erica Madison

At a joint City Council and Alameda Reuse and Redevelopment Authority meeting on Jan. 6, 2009, ACCMA revealed the agency’s $74 million plan to help improve congestion on 23rd Ave.

With help from state-issued infrastructure bonds the Alameda County Congestion Management Agency will use funds to reduce traffic congestion by 277 vehicle hours.

The plan calls for improvements on the 23rd and 29th Avenues on and off ramps.

The ACCMA will reduce congestion by extending the on-ramp at Lisbon back to 29th Ave.

“This will allow for a longer auxillary lane.” Said ACCMA representative.

Extending the auxillary lane will allow on ramp and off ramp traffic to merge.

Extending the on-ramp will mean that a new sound wall will need to be built between 29th and 23rd Avenues. It also means that citizens wont be able to access the freeway from Lisbon or Portwood.

“The traffic that was going into the neighborhood is going to be re-routed underneath the overcrossing and the entrance to the freeway will be right  in front off the shell gas station.” said an ACCMA representative.

Another option the ACCMA has proposed is to install a roundabout at the 29th Ave on ramp.

The Park street triangle  will receive a new traffic signal at Ford and 29th Ave.

The  overpasses will include bike lanes coming and  going. This change will improve the pedestrian walkway.

  1. Capacity for adding left turn pockets
  2. Capacity for adding a Q jump lane
  3. Additional improvements along 23rd ave and park street corridor
  4. Identity capital improvements along corridor.
  5. Improve bicycle and pedestrian facilities
  6. Incorporate q-jump lanes corridor
  7. Use intelligent transportation systems and or smart corridor technology. Develop an intelligent flush plan for the corridor development
  8. Improve the park street triangle operations.

ACCMA plans to finish construction by Oct. 2015.
