| Description | The Wolf River Bridge in Fayette County, Tennessee, crosses sensitive wetlands and carries the only east-west route through its geographic region. For the 20-span replacement bridge, the Tennessee Department of Transportation chose staged construction, maintaining one lane of traffic with timed signals. TDOT designers selected precast prestressed beams to facilitate speedy construction and allowed optional stay-in-place precast prestressed concrete deck forms. TDOT and the contractor developed details for precasting bent caps in two pieces to suit staged construction. Construction of the 1,408-foot long, 46-foot wide bridge was completed in eleven months without putting any equipment in the surrounding wetlands. |

| Advantages | Minimized environmental disruption by eliminating the need to place equipment in surrounding wetlands, and minimized traffic disruption of an important east-west corridor. |

| Contract Elements | "A" plus "B" format was used. The "A" portions of the bids reflected prices for construction items. The "B" portion required the contractor to identify the number of calendar days needed to complete construction, which was then multiplied by a pre-determined price per day established by the owner. |
