Clarkson/Legg Covered Bridge over Crooked Creek- Cullman Co, Alabama

This is a Town lattice truss bridge, 96 years old, 270' two span, and the second longest covered bridge in the southern US. It represents an era of civil engineering dating from 1840 to early 1900. The bridge was built in 1902, repaired extensively in 1922 after flood damage, then completely restored in 1975. In 1974 it was named to the National Register of Historic Places. The bridge carries and will continue to carry pedestrian traffic because of insufficient height and width for other traffic uses. It is bypassed by, but can be seen from an adjacent concrete bridge. The State Historic Preservation Officer (SHPO) has certified that preservation of the bridge is warranted in accordance with SHPO's Statewide historic preservation plan. Major rehabilitation is planned of this bridge including the use of prestressing tendons to reduce creep in the of the lower chords which will be monitored for two years.

Comstock Covered Bridge - East Hampton, Connecticut

This is one of the three remaining covered bridges in Connecticut. Of the three, it is the only one still carrying its own weight with the original timber superstructure. The main span is a 90 ft. long Howe truss built in approximately 1840. It is one of the oldest, if not the oldest, remaining original Howe truss in existence. The truss and floorbeams date from the original time of construction, including the original iron rods. The approach span is a 36 ft. long Queen post pony truss constructed in 1791. The bridge carries pedestrian traffic in a state park setting, and will continue to be a pedestrian bridge after preservation/rehabilitation work. In 1974, major rehabilitation was conducted which included removal of a 12" negative camber, and strengthening of the bridge. The State notes that the negative camber is returning, the truss is getting out of plumb in opposite directions at each end, and the wood has biological deterioration, although the extent is unknown. The State Historic Preservation Officer (SHPO) has certified that preservation of the bridge is warranted in accordance with SHPO's Statewide historic preservation plan.

The work proposed is planned to be conducted in 4 phases:

  1. Study phase - perform detailed inspection and analysis, and make recommendations for rehabilitation
  2. Design phase
  3. Rehabilitation phase
  4. Project report phase

The amount award is for the 'Study phase' ($84,800). Funding of other phases will be considered after reviewing the recommendations at completion of this phase.

Norris Ford Covered Bridge - Rush County Bridge #100, Rush County, Indiana

This is a 148 ft long single span Burr Arch truss built in 1916. It has a clear roadway width of 14.7 ft and serves a mixture of personal, commercial and agricultural vehicles. The floor system consists of two layers Oak deck supported on longitudinal stringers made of Northern Pine. The stringers are supported by transverse floor beams, also made of Northern Pine. The floor beams are supported by trusses made also of Northern Pine. The bridge was built by E.L. Kennedy & Sons and is one of 13 remaining bridges of the 58 built by the Kennedys. The work proposed would rehabilitate the bridge to cater to today's traffic. It would not carry the State's legal load but would be able to carry school busses and emergency vehicles. The rehabilitated bridge would have a 10 ton load limit as opposed to 3 tons, today. Proposed work includes replacing the floorbeams and stringers with glued laminated members; providing supporting bracing of the vertical members and diagonals; and in general strengthening the bridge.

The application states that there are no members of the bridge that use pressure treated lumber. It is strongly recommended that any new wood used on the structure be pressure treated. The State has a historic bridge inventory, but not a formal management plan.

Fitches Covered Bridge - Delaware County, New York

This bridge was originally built in 1870 and located within the Village of Delhi. In 1885 it was dismantled and relocated to its current site about 3 miles north of Delhi to make room for a 'modern' iron bridge. The Fitches bridge is a 100 ft single span, single lane Town lattice style truss open to vehicular traffic with a 3 ton weight limit. It was accepted for inclusion on the National Register of Historic Places in 1999. The Bridge is scheduled for major rehabilitation. Final design is currently underway with plans for completion in 2000, and construction to be completed in 2001. Proposed work includes dismantling the plank lattice trusses to determine the extent of deterioration, and replacement; replacement of bottom chord with sawn lumber; replacement of the flooring; removal of exterior buttresses and insertion of internal bracing system; and replacement of deteriorated concrete caps of the abutment, and retention of the stone abutment. The rehabilitation will upgrade the bridge to a H15 vehicle loading, however the State plans to keep the 3 ton load posting to discourage heavier bridges on the structure. The State is currently in the process of updating its inventory of historic bridges that was completed in 1984.
