F.A.U. Route  7158, Mattis Avenue Over F.A.I. 57

The Illinois Department of Transportation entrusted Bacon Farmer Workman (BFW) with the bridge replacement and roadway rehabilitation of F.A.U. Route 7158, Mattis Avenue over F.A.I. 57. To complete this project, the existing structure, consisting of a 4-span rolled steel beam superstructure with a reinforced concrete deck with open stub abutments on concrete piles, and multi-column reinforced concrete piers supported on spread footings, had to be removed, and the proposed continuous welded steel plate girder structure on multi-column piers and integral abutments had to be installed.

• Old Bridge Structure:
  • 332’-4″ back-to-back abutments
  • 33′-8” out-to-out deck
• New Bridge Structure:
  • 360’-2” back-to-back abutments
  • 54’-10” out to out deck
  • 45° skew

To avoid delays, the construction was accomplished in stages. During Stage I, one lane of traffic was maintained by utilizing a portion of the existing structure. While for Stage II, the portion completed during Stage I would be used to maintain one lane of traffic. To follow IDOT Bridge Manual Sec. 3.2.8 for spans exceeding 150 ft., the positive and negative moments shall be poured separately. Mandatory transverse construction joints will be specified along with a deck pouring sequence. In addition, Temporary Sheet Piling will be designated and detailed according to the 2012 IDOT Bridge Manual. The Temporary Soil Retention system will be designated and detailed for the pier construction sequence, and the Temporary support system will be required of pier cap will be required prior to Stage I removal of the pier. BFW is proud to be able to assist in improving the transportation infrastructure and safety for the Illinois Department of Transportation.
