At a joint City Council and Alameda Reuse and Redevelopment Authority meeting, ACCMA revealed the city’s $74 million plan to help improve congestion on 29th Ave.
In 2006 a statewide infrastructure bond was approved and the Alameda County Congestion Management Agency (ACCMA) was given $74 million to make improvements on the I-880.
The project will be sponsored by the ACCMA in conjunction with Caltrans, the City of alameda, the City of Oakland, and the Metropolitan Transportation Commission.
ACCMA is proposing modification to the I-880 23rd and 29th Avenues on and off ramps
The Alameda County Congestion Management Agency started working on I-880 23rd and 29th Avenues project in 2006. The project will replace freeway overpasses at 23rd and 29th Avenues. The purpose of the project is to make freeway ramps for the northbound I- 880 safer, improve operations, and make it easier for users to navigate through the system.
Public Works has worked with the ACCMA to see how plans to improve I-880 would affect the City of Alameda.
“There are still some concerns.” Said Public Works representative
According to to Public Works staff, access to and from Alameda will be modified with this proposal.
Specifically the proposal poses a significant problem for morning commuters. C informed City council that he asked the ACCMA to present a proposal to the council so they could determine for themselves how Public Works should proceed.
The major objective of the project is to make improvements on the trade corridor, however the ACCMA representative also said it was an opportunity to replace overcrossings.
The 74 million will be used to:
- Replace existing overcrossings at 29th Ave and 23rd Ave.
- Improvement operations and safety along northbound mainline.
- Improve operations and safety at northbound ramps.
- Improve north bound off ramp by Reconfiguring off ramps at 23rd Ave.
- Improve Auxiliary lane between 23rd and 29th Ave.
Making these improvements will reduce mainline congestion and improve safety on freeway on ramps and off ramps. As well as improve improves pedestrian and bicycle circulation. According to the ACCMA the project is also supposed improve access from northbound I-880 into Alameda.
Unfortunately, the ACCMA has not made any improvements to southbound I-880. Their position is that the improvements made on the northbound I-880 will make it easier to do southbound improvements in the future.
With the current configuration lots of accidents happen on the mainline. Currently there is a mainline ramp to the northbound I-880 side only. There are also three main bottlenecks in northbound direction. These bottlenecks cause congestion problems.
Complications due to north bound off ramp at 29th also causes congestion on the mainline.
What’s even worse is that the northbound off ramp on 29th Ave. ends right in front of Oakland’s Lazear elementary school .
ACCMA’s solution is to change the configuration of the off ramps. The new plan is to have traffic exit off a single ramp at a new structure on 29th Ave.
“The overcrossing will become three lanes with addition of a dual left lane.” said an ACCMA representative.
The new overcrossing will allow a dual left turn for people heading to Alameda and a dual right for people heading to east bound 29th.
The plan also calls for an elevated off ramp, which will connect to a new bridge crossing.
