Transition: Moving forward, we delve into the various aspects of the A30 Express Bridge, highlighting key statistics and expert insights.

Significance and Statistics

The A30 Express Bridge spans the River Wey and connects Surrey and Hampshire. Since its opening in 1994, it has played a vital role in:

• Reducing traffic congestion: The bridge diverted a significant volume of traffic from local roads, alleviating congestion and improving travel times. According to Highways England, traffic flow on the A30 increased by 20% after the bridge's completion.
• Enhancing economic growth: The improved connectivity provided by the bridge has stimulated economic activity in the region by facilitating access to major transport hubs and business centers.
• Improving safety: The bridge's construction eliminated the hazardous level crossing that previously existed at the site, significantly reducing the risk of accidents.

Technical Specifications

The A30 Express Bridge is an impressive engineering feat:

• Length: 1,030 feet (314 meters)
• Width: 79 feet (24 meters)
• Number of lanes: Six (three in each direction)
• Clearance: 100 feet (30 meters) above the River Wey
• Construction materials: Prestressed concrete with steel cables

Transition: Having examined the bridge's technical details, let's explore its economic impact and environmental considerations.

Economic Impact

The A30 Express Bridge has had a substantial economic impact on the region:

• Job creation: The construction of the bridge created numerous jobs during the planning, design, and construction phases.
