Installation:

November 12, 2003

As part of Maple Valley’s “Signature Street” program, a CON/SPAN® precast arch tunnel was selected to connect a new subdivision to cross an existing jogging/equestrian trail. Residents of the subdivision now have direct access to the highway, and the structure provides two new access ramps to the King County trail. The grand opening of the bridge was celebrated with a ribbon cutting ceremony.

“This new bridge helps connect the city visually and also connects people traveling by either car or by foot” said City Mayor Laure Iddings. “Visually, the CON/SPAN structure echoes the other design features that the city of Maple Valley is adopting as its visual signature...and this style will be repeated in future developments as well” The CON/SPAN® structure includes decorative bridge railings and end columns, landscaping enhancements and ornamental light standards and benches. The simulated rock facing on the tunnel and retaining walls mimics a natural stone appearance at 70% of the cost. Installation was completed within the city’s deadline and budget.
