In 2014, the Howard County Department of Public Works determined the need to renovate and repair the pedestrian and bike bridge crossing US 29 that links Columbia Town Center with the residential communities east of the highway. The existing chain-link fence barrier around the bridge was unappealing to users and motorists who crossed over and under it every day. Poor lighting contributed to the community's concerns about safety and security. Following feasibility studies and community input meetings where four options where presented, the County moved forward with the overwhelming design choice voiced by community members that featured a spiraling geodesic tube surrounding the bridge with Cambridge Architectural metal mesh. 


Cambridge wove 686 Tartan mesh panels (5,043 square feet) with 77% open area. The stainless steel mesh was attached to a round bar frame with mounting tabs on a custom system created by Geometrica. Select panels of mesh were powder-coated green, blue and white to add to the crossing's design. By mixing powder into paint, the coating was applied to the mesh and baked in an oven at a high temperature which caused the powder to melt and bleed into the paint. This technique provides a long-lasting, weather-resistent barrier that protects against abrasion, scratches, chips, fading and corrosion.


The mesh not only provides fall protection for walkers and bikers but also prevents objects from being thrown from the bridge that could damge automobiles and injure highway drivers below. Upgraded lighting was affixed to the round bar frame to illuminate the bridge patchway for nighttime users.
