The Carlin Springs Road Bridge, over N. George Mason Drive, while still structurally sound, has shown the greatest deterioration of any of the County-owned bridges. The County will be undertaking a complete replacement of the existing bridge. The rehabilitation project will focus on much-needed structural improvements and new safety features for motorists, pedestrians and bicyclists.
In 2010, the County Board approved the rehabilitation of the Carlin Springs Road Bridge over N. George Mason Drive. Design consultants were hired and are working with County staff to prepare recommendations for the proposed rehabilitation.
As part of the design process, a community meeting regarding this project was held in September of 2011. At that meeting, County staff presented three concept design alternatives and solicited community input on the project design and implementation.
A preferred design (PDF) for the bridge was selected that will:
The new design includes a final cross-section that will be 69' wide, a slight increase from the existing 65' bridge width.
Following the selection of a "preferred design", staff solicited input from the community regarding the aesthetic design elements of the bridge, using both an online survey (over 600 people completed the survey) and by holding a public meeting in June of 2012. The public input process for the aesthetic design for the bridge was completed in the summer of 2012 and a short report on the online survey findings (PDF) >> has been produced.
A 90% design for the bridge has recently been completed. The drawing (PDF) shows how the proposed bridge may appear when viewed from George Mason Drive.
County staff sought to include the design recommendations that were collected via the public survey. Ultimately the preferred facade material of Ashlar stone proved to be infeasible due to the substantial additional construction expense and the anticipated additional traffic disruptions. The proposed design utilizes cast concrete and incorporates many of the design recommendations provided by the community, particularly those pertaining to the arch, decorative railing, street lights and inclusion of the street name. County staff believe that the proposed design will be an aesthetic enhancement to the roadway.
County staff will continue to work during the early part of 2014 to complete the engineering of the bridge. The final Design Plans are currently being developed to sequence construction of the new bridge, and demolition of the old, in the best manner to maintain traffic safety and access while minimizing negative impacts upon the community. It is anticipated that construction will begin on the new bridge in late 2014 and would require about one year to complete.
Carlin Springs Road Bridge is one of 25 County bridges supporting vehicular traffic in the National Bridge Inventory System. Arlington is one of only two Virginia counties that own and maintain their own bridges. Each of these 25 bridges is inspected biannually.
Built in 1961, the Carlin Springs Road Bridge provides pedestrians and bicyclists with an important connection between the growing urban village of Ballston and the Bluemont, Arlington Forest, and Buckingham neighborhoods. The bridge also gives motorists and public transit vehicles access to major commuter routes such as I-66 and Arlington Boulevard.
