The Westlink Industrial Drive Bridge replacement project is located near a manufacturing company in the Westlink Industrial Park.  The company hauls heavy transformers over the bridge weekly to a nearby railroad for shipping purposes. We were selected to design a structure with an increased load carry capacity, greater than the initial HS20 loading specification, so the company could continue shipping.  Addition structural calculations were necessary to size and reinforce the bridge members to handle the heavier truck loading requirements.
