Bardwell's Ferry Bridge
Conway and Shelburne, Massachusetts
Designer: STV/Seelye Stevenson Value & Knecht
Contractors: Koch Construction, Greenfield
Constructed in 1882, this is one of the oldest and longest
span lenticular truss bridges remaining in the United States.
When rehabilitation was planned, it was discovered that substantial
repairs were needed. Discreet reinforcement of deteriorated
truss members and floor beams, replacement of only those elements
which could not be repaired, and repainting the superstructure
in an historically appropriate deep red color were just a few
of the sensitive treatments this bridge received. |

Assateague Island Pedestrian Bridge
Worcester County, Maryland
Designer: Wallace, Montgomery and Associates / Whitney, Bailey,
Cox, and Magnani - Joint Venture, Towson
Contractors: McLean Contracting, Glen Burnie
A safety study showed the best way to improve the safety and accessibility
of pedestrians and bicyclists to Assateague Island National Seashore
was to build a separate bridge parallel to the existing roadway
structure. The design of the piling system minimized the disturbance
to the natural environment of Sinepuxent Bay. The structure was
also designed with an observation platform at the bridge's crest
overlooking the boating channel. The platform also presents park
users with a vista of the barrier island as well as an educational
opportunity. |

Five Mile Bridge - Old Stage Road over the Illinois and Michigan
Canal
Morris, Illinois
Designer: Graef, Anhalt, Schloemer & Associates, Chicago,
Illinois
Contractors: Belvidere Construction, Belvidere, Illinois
This innovative structure is the first timber arch bridge in Illinois.
The arches, beams, and deck are pressure-treated, glue-laminated
southern yellow pine, a material compatible with the rustic environment
of this national heritage corridor. The innovative use of a steel
rod cross-bracing system hidden just below the deck is used to
carry lateral loads to the bridge's abutments. |

The Grasshopper Bridge
Phoenix, Arizona
Designer: Cannon & Associates, Phoenix
Artist: Ed Carpenter, Portland Oregon
To ensure that children would use the bridge across a large wash,
the city used an artist to develop an innovative, playful design
that is integrated into the structural design. Because the children
designed templates for desert insects, lizards and animals that
were sandblasted and stained onto the concrete deck, the children
use the bridge and treat it with respect. |

Portland Avenue Bridge
Beloit, Wisconsin
Designer: Westbrook Associated Engineers, Spring Green, Wisconsin
Contractors: Zenith Tech, Inc. Waukesha, Wisconsin
The Portland Avenue Bridge is an example of incorporating design
considerations with sensitivity to the existing site. Because
it is located within Beloit's riverfront revitalization project
aesthetics were extremely important. The ornamental railing, distinctive
lights, limestone surfaces, exterior girder staining, and flared
overlooks are noteworthy features of this attractive bridge. Endangered
species and hazardous materials in the Rock River also required
innovative design. |

Second Blue Water Bridge
Port Huron, Michigan
Designer: Modjeski and Masters, Pennsylvania;
Buckland & Taylor, British Columbia
Contractors: Ellis-Don, PCL/MC Carthy A Joint Venture;
Walter Toebe Construction Co.
The original Blue Water Bridge was built in 1938 and is a highly
visible historic landmark that carries I-94 across the St. Clair
River to Canada. A comprehensive public participation program
considered various alternatives and recommended a continuous tied
arch design. The selection complemented the original bridge without
compromising its historical integrity. |

Wabasha Street Bridge
St. Paul, Minnesota
Designer: Figg Engineering Group, Tallahassee, Florida
Contractors: Lunda Construction Company, Black River Falls, Wisconsin
This cast-in-place post-tensioned segmental concrete structure
is a signature bridge for the city of St. Paul and the centerpiece
of the downtown redevelopment. It not only meets the desired aesthetic
requirements but also demonstrated the adaptability of the concrete
segmental construction method to large seasonal temperature variations.
The project broke new ground by placing concrete during one of
the worst Minnesota winters in modern times. |

Main Street Bridge
Pen Yan, New York
Designer: Bergmann Associates, Rochester
Contractors: Crane Hogan Structural Steel Systems, Spencerport
This replacement bridge over the Keuka Lake outlet and pedestrian
trail was designed to complement nearby historic buildings and
sites. It also incorporated much of the stone facing material
that was saved from the original bridge. The bridge spans a pedestrian
trail that allows users to enjoy the beauty of the stone arches
from a vantage point below the structure. |

Columbus Front Door Project
Columbus, Indiana
Designer: J. Muller International, Chicago
Contractors: Milestone Contractors, Columbus
This innovative twin ribbed steel, cable-stayed arch bridge meets
the design requirements for a clear span over the single point
interchange. Clearly visible from both I-65 and State Route 46,
it serves as a welcoming landmark for the entrance to the city
of Columbus - long noted for its rich architectural heritage.

State Route 509 Relocation
Tacoma, Washington
Designer: Washington State Department of Transportation
Contractors: Max J. Kuney, Spokane;
Scarsella Brothers, Seattle;
Walter and Sci, Renton;
Ames Construction, Burnsville, Mn;
Tucci and Sons, Tacoma;
A.H.Powers, Seattle
Significant traffic delays on old State Route 509 through the
port of Tacoma led to the design of this 4.5 mile divided highway.
The new facility improved safety, traffic flow, and provided direct
access to Interstate Route 705. The cable stayed bridge, a design
requested by the city, minimized impact to a superfund cleanup
site and gave the city a "landmark" structure.
