Custom design/build bridge solutions that ship and install easily. 

Big R Vehicular Bridges from AIL are ideal for transportation and public works applications as local crews using on-hand equipment can typically place the superstructure in one day – reducing costs, equipment time and road closure time.

Spans from 4.9 m (16') to over 45.7 m (150') are available in any width. Superstructures can be fabricated with both square and skewed ends to suit any site conditions.

Modular Concrete Deck Options

When concrete decks are required, the superstructure is manufactured with steel girders complete with shop-installed shear connectors and stay-in-place forms. After the superstructure is erected, rebar is installed and a concrete deck can be poured by the customer’s contractor. Precast concrete deck panel options are also available.
