CTDOT List 22-25 Bridge Design

statewide, ct

AI is providing CTDOT with design services for the List 22-25 Bridge Design Assignment. Under this assignment AI is preparing final design plans, specifications and construction cost estimates for the rehabilitation of five (5) bridges in the Towns of Enfield, Stratford, Waterbury, and Waterford, CT. AI is also responsible for the design of the approaches to these bridges including maintenance and protection of traffic during construction, hydraulic analysis and storm sewer design traffic engineering. The extent of work for these bridges varies from substructure and superstructure repair to complete structure replacement. These structures carry or cross over active railroads of Interstate highways creating complex construction sequencing and staged construction drawings. The work includes, but is not limited to, horizontal and vertical alignment modifications including widening. The bridges include the following:

  • Bridge No. 00326, U.S. Route 1 over Metro North Railroad, Stratford
  • Bridge No. 03361, U.S. Route 5 over CT Route 190, Enfield
