Flat Faced Chain and Cut Resistant Pad Lock

Most cyclists – whether commuting to work or running errands on the weekend – worry about bike theft. It is a real concern in the Bay Area and something many of us has experienced first-hand.  Bicyclists often ask, “what is the best way to lock up a bicycle to keep it from being stolen?”
There is no single answer that fits all situations but according to a recent article in Popular Mechanics titled, Can you Buy a Bolt Cutter-Proof Chain?  the author, Roy Berendsohn, discusses security in general and explains how to find cut-resistant chains and padlocks. A cut-resistant chain is “hardened throughout its thickness, and its flat face distributes the force of the bolt cutter’s jaw over a wide area, thereby diffusing it.” There are several different types of locks out there, and this is just one option. It might be heavier to carry around but harder, if not impossible, to break with common cutters.
Once you’ve got an ideal lock, you still need to find something to lock your bike to.  This quora thread discusses the safest way to lock a bike and suggests some things to consider when locking your bike.
Occasionally we hear stories about thieves cutting chains or popping U-locks. Recovering a stolen bike can be difficult and replacing it (or just replacing a stolen wheel) can be  expensive.  511 Contra Costa encourages novice and experienced riders alike to take advantage of the many benefits of cycling. However it is important to stay safe both on the road or trail, and with the right tools, including a good lock and safe riding techniques, you can minimize the risks and focus on having a nice ride.

Pleasant Hill Man drives a half million miles in vanpooling between Pleasant Hill and San Francisco

Roger Matoba’s of Pleasant Hill was honored by MTC for operating a commuter vanpool for 29 years.  Roger proudly named his vanpool vehicle after the Japanese word Ichivan, meaning Number One.  Departing from Pleasant Hill early each morning, Roger drove over 100 varpoolers to/from work in San Francisco for nearly three decades. It is estimated that the IchiVan traveled an estimated half million miles before retiring earlier this year.
Matoba and his ItchiVan vanpool was recently honored by the Metropolitan Transportation Commission with the Miriam Gholikely Public Service Award for his 29-year contribution to Bay Area transportation.

511 Contra Costa is proud to have nominated Roger and his IchiVan as an example to live by in reducing congestion and auto emissions saved by carrying many passengers!

Caldecott Tunnel Excavation Completed

On September 21, 2012 – almost exactly two years from the start of tunneling – all excavation of the Fourth Bore was completed. An update on tunnel progress with photographs and additional information can be downloaded from our website (PDF).

The tunnel now measures almost 10 meters (33 feet) high and 13 meters (43 feet) wide for its entire length. Crews are currently working around the clock to complete the installation of a waterproof membrane to prevent groundwater seepage, as well as a rebar cage and final lining arch, which will provide both flexibility and strength in the event of an earthquake. The final lining, which requires a total of 69 concrete pours, or “lifts,” is what motorists will see as they travel through the tunnel.

Although we are pleased with the significant progress to date, there is still much work to be done before the tunnel is ready for traffic in late 2013. This work includes paving of the roadway inside and outside of the tunnel, completion of the portal arch on the tunnel’s eastern end, as well as the installation, configuration and integration of electrical, drainage and ventilation systems. These operational and safety systems will be controlled from the new state-of-the-art Operations and Maintenance Control building. Crews will also construct a permanent sound wall in Oakland measuring 2.5 meters (eight feet) high and 161 meters (528 feet) long.

When the tunnel is completed, its eastern and western portals will be adorned by medallions. The medallion designs will be influenced by artwork provided by young residents in Alameda and Contra Costa counties.

For detailed information on the progress of the Fourth Bore’s construction, please see the Fall Project Update, which is available for download here (PDF). Please continue to visit the website for updates on tunnel progress.

Over the next three months, Caltrans and its partners, the Contra Costa Transportation Authority and the Alameda County Transportation Commission, will host ceremonies for participants in the medallion design contest in both Alameda and Contra Costa Counties, and the Caldecott Tunnel project team will mark the 75th anniversary of the Caldecott Tunnel’s first two bores. If you have friends or neighbors who would like to stay updated on the project, please ask them to sign up for these email alerts at www.Caldecott-Tunnel.org/stay-informed/contact-us.

The Caldecott Fourth Bore Project is a partnership between the Federal Highway Administration, the California Department of Transportation, the Metropolitan Transportation Commission, the Contra Costa Transportation Authority, and the Alameda County Transportation Commission.

<a name=”winners”></a><h2>Previous questions and winners</h2>
<strong><a href=”https://511contracosta.org/caldecott-tunnel-trivia-question-1/”>Question 1 (deadline: October 20, 2011)</a></strong>
The topheading from both the east and the west is being excavated now, and that work will be followed by the bench, or bottom portion.
<strong>Q:</strong> Why is the top section of the tunnel being excavated first?
<strong>A:</strong> By excavating the top section of the tunnel first the miners maintain better control of the surrounding rock, which allows more efficient tunneling.
<strong>Winner:</strong> Roxanne R.
<strong><a href=”https://511contracosta.org/caldecott-tunnel-trivia-question-2/”>Question 2 (deadline: November 3, 2011)</a></strong>
The Caldecott Fourth Bore Project is composed of four construction contracts. The project to build the Fourth Bore tunnel is by far the largest but several other contracts are included that improve traffic flow in the area. These include:
Kay Street Project
Route 24/Highway 13 Interchange Project­
<strong>Q:</strong> What is the 4th contract?
<strong>A:</strong> Landscaping Project
<strong>Winner:</strong> Stephanie V.
<strong><a href=”https://511contracosta.org/caldecott-tunnel-trivia-question-3/”>Question 3 (deadline: November 21, 2011)</a></strong>
The Caldecott Fourth Bore Project is one of the nation’s largest ARRA investments with the receipt in $180 million in ARRA funds.
<strong>Q:</strong> What is the second largest source of funding for the project?
<strong>A:</strong> Contra Costa Measure J accounts for $122.5 million of the project’s funding. Contra Costa voters passed the Transportation Expenditure Plan in November 2004.
<strong>Winner:</strong> Thomas S.
<strong><a href=”https://511contracosta.org/caldecott-tunnel-trivia-question-4/”>Question 4 (deadline: December 5, 2011)</a></strong>
The Caldecott Tunnel traverses a heavily traveled portion of State Route 24 between Alameda and Contra Costa Counties.
<strong>Q:</strong> How many vehicles travel through the Caldecott tunnel every day?
<strong>A:</strong> State Route 24 carries about 160,000 vehicles per day traveling through the three tunnels. The new fourth bore will relieve congestion in the off-peak direction (eastbound in the morning and westbound in the afternoon), and eliminate the need to switch the direction of traffic flow in the middle bore to accommodate shifting traffic demands.
<strong>Winner:</strong> Julie D.
<strong><a href=”https://511contracosta.org/caldecott-tunnel-trivia-question-5/”>Question 5 (deadline: December 19, 2011)</a></strong>
The Fourth Bore Project recently celebrated a major milestone with the tunnel “breakthrough”.
<strong>Q:</strong> What does this significant milestone represent for the project?
<strong>A:</strong> Breakthrough marks the completion of topheading excavation and demonstrates the tremendous progress the project has made since tunneling began. For more information about the breakthrough visit the <a href=”http://www.caldecott-tunnel.org/index.php/construction/tunnel-breakthrough” target=”_blank”>Fourth Bore website</a>.
<strong>Winner:</strong> Karen H.

Caldecott Fourth Bore Progress Update

 

According to the graphic depicting progress on tunneling, work crews have excavated more than 300 meters. The graphic shows mining of the topheading at the eastern and western portals of the tunnel.
Breaking through a three-foot thick concrete retaining wall, tunneling crews began excavation on the western side in mid-March, as work on the eastern side continued to make headway. Excavation of the Orinda Formation has been completed and tunneling through the Claremont Foundation is well underway.
Tunneling from the west presents new challenges. The less stable rock formation requires the installation of structural reinforcements at shorter intervals than on the eastern side.
