It has gone from an afterthought to one of the biggest issues in town. The impact of I-80’s increased traffic and the increasing rate of cut-through traffic has led to more people using bypasses, exacerbating congestion on Mace and other surface streets.
On Thursday, Caltrans hosted an open house at the Blanchard Room – it was well attended by the public, which had a chance to submit comments.
According to city officials, the project would then go to an EIR, but the expectation is that this is a project that is at least ten years out – not something that is going to help improve traffic conditions in the near-term.
On Tuesday, Adrian Engel from Fehr & Peers pointed out “some of the congestion can be mitigated with the solutions that we have, but all of it will not be mitigated.” The key is there will be “freeway congestion that causes queuing onto the corridor.”
He explained that he and his team got onto the freeway during peak time to validate that the freeway was not the fastest way to get from Dixon to the Causeway. Five of them traveled at the same time through different routes to see if the apps and maps and Waze “were telling us the true story.”
Traveling on the freeway was indeed the longest time. Some of the other routes “were definitely faster than the freeway.” The fastest they found was Highway 113 and County Road 29 to bypass the queue. They found that to be almost 15 minutes faster.
“There are multiple ways that can be used to bypass this freeway traffic,” he said. “The software that’s giving you these alternate routes is true and we have verified are actually faster. Ultimately the solution for this problem is going to fix I-80 and getting that traffic to flow better to keep cars on the freeway. Because if you fix Mace or do something to Mace, it may just cause traffic to go in other places.”
ALTERNATIVE / 1A
- Kidwell Road to Solano/Yolo Co. line, convert one mixed flow lane to managed lanes;
- Solano/Yolo County Line to west end of the Yolo Causeway, pave median and widen to the outside to add managed lanes;
- Yolo Causeway to east of Enterprise Boulevard, remove existing bike lane, restripe bridge to add managed lanes, construct separate pedestrian/bicycle bridge;
- East of Enterprise Boulevard and continuing on 1-80 to West El Camino Avenue, add managed lanes by constructing a connector and striping managed lanes on paved median, construct a park-n-ride lot at Enterprise Blvd., restripe Bryte Bend bridge to add managed lanes;
- 1-80/US 50 Separation to Jefferson Blvd. Undercrossing, convert mixed-flow lanes to managed lanes; and
- Jefferson Blvd. Undercrossing to just east of Interstate 5, restripe pavement to add managed lanes.
ALTERNATIVE / 1B
- Same as Alternative 1A except widen Yolo Causeway for bike/ped instead of new bridge.
ALTERNATIVE / 1C
- Same as Alternative 1A except use existing Yolo Causeway bike/ped facility and restripe Yolo Causeway with Managed Lanes in each direction.
ALTERNATIVE / 1D
- Same as Alternative 1A, except widen median between Kidwell and Solano/ Yolo Co. line.
ALTERNATIVE / 2
- Interim EB Reversible Lane from just west of Yolo County Line to Enterprise Blvd. convert mixed flow lanes to Managed Lanes on US50 to 1-5 I/C.
ALTERNATIVE / 3
- Interim project, similar to Alternative 1 A except widen median only between Yolo County line and Yolo Causeway, no new bike/ped bridge or managed lane to managed lane connectors· at the 1-80/US 50 1/C.
ALTERNATIVE / 4: Interim project, stripe managed lanes on Bryte Bend bridge.
ALTERNATIVE / 5: Same as Alternative 1 A, except use managed lanes exclusively for transit use.
ALTERNATIVE / 6: Same as Alternative 1 A, except construct two managed lanes in each direction.
ALTERNATIVE / 7: No Build.
Additional scope to be studied as part of the alternatives include the following:
- Auxiliary lane from southbound 113 to eastbound 1- 80 and Richards Blvd
- Convert one existing general-purpose lane in each direction to managed lanes
- ‘Westbound 80 Auxiliary Lane from Jefferson Blvd to Harbor Blvd
- Transit connectivity to mainline
- Ramp meters, CCTV, Changeable Message Signs
