<a name=”winners”></a><h2>Previous questions and winners</h2>
<strong><a href=””>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=””>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=””>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=””>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=””>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=”” target=”_blank”>Fourth Bore website</a>.
<strong>Winner:</strong> Karen H.
