Bridge Facts
Community Bridge now contains:
- More than 3,000 stones, no two of which are alike
- Four major features (including a bronze gate, a sculpture in a
niche, a marble fountain and a special type of a perspective painting
called an anamorphic projection) and numerous minor ones
- 160+ carvings of community ideas, representing about 1000 people
residents
It covers:
- Approximately 3,000 square feet
- Both face walls and all supporting walls of the Carroll Street
Bridge,
with mural sections facing north, south, east and west
Time frame:
- The muralist began working full time on the project in February
1993. The bridge
was completed in September 1998, although symbols continue to be added occasionally.
Surface preparation
- The supporting walls of the bridge were resurfaced with a three-coat
rough finished cement stucco system on metal lathe, which was
applied by plasterers.
- For added strength and durability, the
new surface was subjected to a 30-day wet cure process.
- The bridge face walls presented more difficult challenges, due
to the multiple stresses such walls are subject to, such as extreme
thermal variations and traffic vibration. Fiberglass-reinforced
cement panels on metal lathe were installed on the bridge face
walls, providing a surface that is held one inch away from the
underlying bridge, thus isolating the mural surface from the bridge
surface.
- Waterproofing measures included asphalt-coated copper fabric flashing,
aluminum flashing, extensive caulking, waterproof membranes lining
the subgrade surfaces of all wing walls, and drainage measuress.
Paint:
- Potassium silicate-based Keim paint from Germany
- The pigments used in Keim are absolutely lightfast, and the paint
is not affected by air pollution or acid rain.
- Murals painted with potassium silicate paint in the late 1800s
in Germany and Switzerland have survived handsomely to the present
day.
- Approximately 150 gallons of paint, primers and pretreatments
were used during this project.
Artists:
- Cochran employed ten
assistants, most worked
for only two or three weeks, but each of whom made important contributions
to the project.
- One assistant, Pam Jaffee, became the project's "ivy specialist"
and spent nearly six months painting nothing but ivy leaves on
the bridge.
- Several artistic consultants made important creative
contributions to the work including William Swetcharnik, who advised on certain general artistic and technical matters, and Ann Zeleny, who designed the wreath found in The Forgotten Song, as well as the borders on several of the mdeallions, and made a scale model of the fountain bowl from Cochran's drawings.
Funding:
- The City of Frederick: $122,000
- Frederick County: $22,000
- Shared Vision (through many corporate and private donors):
$145,060+, including:
- Maryland State Arts Council: $20,000
- The Rotary Club of Carroll Creek: $50,000 to put us over the top!
The total cost of the project is $300,000. Another $200,000 worth of in-kind (donated) goods, services, materials and labor were contributed by the community to accomplish the non-painting aspects of the work, including the Bridge Builders' outreach, the exhibit, the events and final celebration, the website and other publications, etc. The artwork has been estimated to be worth more than one million dollars.
be worth as much as one million dollars.
