On Monday, May 22nd, Contra Costa County will host a community workshop on the I-680/Treat Boulevard Bicycle and Pedestrian Improvement Plan.
The goal is to identifiy improvements to serve bicyclists and pedestrians using the Treat Boulevard/I-680 corridor between the Iron Horse Trail, through the Interstate-680 (I-680) over-crossing near the Contra Costa Centre/Pleasant Hill BART station area, and extending west to Geary Road/North Main Street in the City of Walnut Creek.
Since the I-680/Treat Blvd overcrossing is one of the main arteries into the Contra Costa Centre/Pleasant Hill BART area from areas of Walnut Creek west of the freeway, residents and commuters are encouraged to attend this meeting and give feedback.

Construction: I-680 from Walnut Creek to San Ramon (Through Fall 2016)
Construction of a portion of the Bay Area Express Lanes on I-680 (between Walnut Creek and San Ramon) has begun and is scheduled to last approximately 15 months. Construction includes installation of variable message signs and overhead toll readers, concrete foundations for overhead freeway sign structures, and laying conduit and fiber optic communications cables for traffic management system communications.
The Metropolitan Transportation Commission (MTC) is scheduling construction work so that it will have minimal impacts on traffic. Construction will mainly occur at night, although there may be occasional activity on the shoulder and on arterial streets adjacent to the highway during the day to complete the communications network. Nighttime construction will typically involve closing one or two highway lanes, depending on the nature of the work.
Express Lanes are specially-designated highway lanes that offer toll-free travel for carpools, vanpools, transit, motorcycles and eligible clean air vehicles. Solo drivers also have the choice to pay a toll to use the lanes for a more reliable trip. The Express Lanes between Walnut Creek and San Ramon will have an open access configuration, similar to HOV lanes.
The I-680 Express Lanes between Walnut Creek and San Ramon are scheduled to open in fall of 2016. For more information, you can visit bayareaexpresslanes.org or email info@bayareaexpresslanes.org to request project updates.
Construction is a dynamic process and information is subject to change without notice. Work is subject to weather conditions.
Southbound I-680 Marina Vista Ramp Closure: May 4 – October, 2015 (Martinez)
On May 4, a closure and detour will go into effect for the southbound I-680 Marina Vista/Waterfront Rd off-ramp in Martinez. The closure will remain in effect until October 2015. Between April and October, a seismic retrofit will be performed on the Mococo Overhead Bridge and the I-680 off-ramp will be replaced.
During the closure, southbound I-680 traffic will detour to the Arthur Road interchange, exit and cross under the freeway, return to northbound I-680, and exit at Marina Vista/Waterfront Road. Marina Vista and Waterfront Road will remain open during the extended ramp closure.
Please allow extra travel time when driving through this area and make sure to Slow for the Cone Zone. For more information about the project, visit the Caltrans Mococo Overhead Bridge Project webpage.
NOTE: Post edited to reflect postponement of closure to Monday, May 4.
Advisory: I-680 Mococo Overhead Bridge Project Lane & Ramp Closures (Mar. 2015)
Caltrans District 4 has scheduled the following lane and ramp closures for the Interstate 680 Mococo Overhead Bridge Rehabilitation Project:

Upcoming Closure of Southbound I-680 Off-Ramp to Marina Vista/Waterfront Road
In late April 2015 Caltrans will close the southbound off-ramp from I-680 to Marina Vista/Waterfront Road. The closure will remain in effect for about five months while the contractor removes the old off-ramp structure and builds a new structure.
- Detour: During this closure, southbound I-680 traffic will detour to the Arthur Road interchange, exit and cross under the freeway, return to northbound I-680, and exit at Marina Vista/Waterfront Road
- Marina Vista and Waterfront Road will remain open during the extended ramp closure
Please drive cautiously through the construction zone, follow the directions of flaggers, leave a safe traveling distance between your vehicle and the vehicle ahead of you, and Slow for the Cone Zone. The California Highway Patrol will be on site during these closures.

Contra Costa HOV Lanes on I-680 to Be Converted to Express Lanes (2014)
The Bay Area Infrastructure Financing Authority (BAIFA) is working closely with Caltrans to convert the existing HOV lanes on I-680 into express lanes from Rudgear Road to Alcosta Blvd. in the southbound direction and from Alcosta Blvd. to Livorna Road in the northbound direction. Like existing HOV lanes, express lanes are FREE for carpools, vanpools, buses and other eligible vehicles while allowing solo drivers to use the lanes for a toll.
Open House
BAIFA invites everyone to attend an informational meeting to learn more. Project plans will be on display and project team members will be present to provide input about the project.
Thursday, January 30, 2014
5:30 – 7:30 p.m.
San Ramon Community Center at Central Park
12501 Alcosta Blvd. San Ramon, CA 94583
OnLine Public Open House
Can’t make the meeting in person? BAIFA is also hosting an online public meeting at www.BAIFAexpresslanes.org that will begin January 30 and be open for two weeks, closing February 13. The online format will allow the public to view the same information that will be shown at the public meeting and provide input during the two-week period. Once on the project website, click the link to view the information.

I-680 construction underway
Are you in one of the 170,000 vehicles that passes across I-680 every day? Is your suspension still reeling from the potholes and cracks? You’re in luck.
Caltrans began work in January rehabilitating 12.8 miles of freeway from Alcosta to Rudgear. Caltrans is also expanding the HOV lane on the southbound side about one mile form Livorna Road to just short of Rudgear Road.
Both projects are expected to finish in spring 2012.
Most construction will take place at night, and barriers will be in place during the day, but don’t forget to “Slow for the Cone Zone.”
The general work windows vary slightly by location.
Work window from Alcosta Blvd. to Sycamore Valley Road
Mon. – Fri. 8 p.m. to 6 a.m.
Sat. 8 p.m. to 9 a.m.
Sun. 8 p.m. to 10 a.m.
Work window from Sycamore Valley Rd. to El Pintado Rd.
Mon. – Fri 7 p.m. to 6 a.m.
Sat. 7 p.m. to 9 a.m.
Sun. 7 p.m. to 11 a.m.
Work window from El Pintado Rd. to Rudgear Road
Mon. – Fri. 8 p.m. to 6 a.m.
Sat. 8 p.m. to 8 a.m.
Sun. 8 p.m. to 11 a.m.
With 7,300 cubic yards of pre-cast concrete, this will be the largest application of this innovative treatment in the US. Pre-cast slabs are expected to reduce the need for long-term maintenance, and can be driven over immediately – no need for drying time.
$72 million of the rehabilitation and HOV project is funded by the CA State Funding for Roadway Rehabilitation (SHOPP) program, plus $1.8 million from Contra Costa County Measure J (half-cent sales tax).
Portions of I-580 and I-680 closed this weekend
This weekend, July 17 and 18, BART and Caltrans will close a portion of Interstate 580 and 680 between Dublin and Pleasanton.
Crews will be working to complete installation of pedestrian bridges that will provide access to the new West Dublin station.
Eastbound I-580 from the San Ramon/Foothill Road exit will be closed and on the I-680 interchange, partial lane closures will begin at 11 p.m. each Saturday night. The lanes will be completely closed from 2-6 AM each Sunday and will resume with partial closures until 9 AM.
If you are driving on eastbound I-580 during the closure, follow detour signs to use Foothill Road to Stoneridge Drive.

Speeders on I-580 and I-680 face CHP crackdown
“Am I going to get pulled over? I see a lot of CHP officers on I-580 and I-680…”
According to a recent column in the Contra Costa Times:
Since January of 2010, the CHP has deployed speed teams six times in Contra Costa County and written about 1,000 speed citations.
The teams target violations that play a large role in collisions, such as speeding, tailgating and driving under the influence. However, the teams have been operating for years and target different spots along the highway. If you’ve been seeing a lot of officers, it’s probably just by chance rather than there being an actual increased number of them.
For the full question and answer, read Speeders facing a CHP crackdown in the Contra Costa Times’ Queen of the Road column.
