Bridge girder with high central-wall-beam

A bridge girder between two piers for transporting vehicles with a first and second wheel-path, comprising:

• a central beam located at the median of the bridge, the central beam extending upward from the bridge deck to a height greater than the height of vehicles traveling on the bridge, the central beam having a width less than its height to define a tall, slender load-bearing element, the central beam being configured to suspend and support a majority of the weight and load of the bridge and to transfer the forces thereof to the piers;
• a first road deck located on one side of the central beam, the first road deck including a first lane for a first direction of vehicle traffic, the first lane comprising a first runway located under a vehicle's first wheel-path and a second runway located under the vehicle's second wheel-path;
• and
• an opening section extending between the first and second runways of the first lane and allowing air, rain, or snow to flow through the deck so as to reduce surface accumulation and aerodynamic uplift.
