Design
The tunnel, which is more of a "table" design rather than an actual tunnel, is divided into two tubes, each carrying five lanes of one-way traffic flanked by two emergency lanes. Each of the two tubes can carry up to 16,000 vehicles per hour. Between the two tubes exists a single-lane tube that was designed as an express terminal for city buses. The tube is unused, and the approaches on both sides of the tunnel are gated off.
