    Indian Hill Road Bridge Replacement

    The City of Lynchburg plans to replace the Indian Hill Bridge over Ivy Creek due to ongoing deterioration.  Along with the replacement of the bridge, design services shall also include esthetic upgrades to both the bridge structure and the adjoining roadway. Some of the new feathers would include a sidewalk across the bridge, a roundabout, landscaping and improved street lights. This structure was constructed in 1960 with no major rehab work taking place.  The bridge itself consists of two lanes crossing over Ivy Creek.  This structure serves as an internal connection for the Evergreen Subdivision.

    This structure has an overall condition rating of very poor; it is structurally deficient and functionally obsolete. The deck and substructure exhibit cracking, spalling and delamination throughout. Rust and corrosion is present on all of the girders with the most server section loss located adjacent to the bearings.

    What is a “structurally deficient” bridge? Bridges are considered structurally deficient if they have been restricted to light vehicles, closed to traffic or require rehabilitation. Structurally deficient means there are elements of the bridge that need to be monitored and/or repaired. The fact that a bridge is "structurally deficient" does not imply that it is likely to collapse or that it is unsafe. It means the bridge must be monitored, inspected and maintained.

    How is “structural deficiency” determined? The condition of different parts of a bridge is rated on a scale of 0 to 9 (with 9 being “excellent” and zero being “failed”). A structurally deficient bridge is one for which the deck (riding surface), the superstructure (supports immediately beneath the driving surface) or the substructure (foundation and supporting posts and piers) are rated in condition 4 or less.
     
    What makes a bridge structurally deficient, and are structural deficient bridges unsafe? The fact that a bridge is "structurally deficient" does not imply that it is likely to collapse or that it is unsafe. A “deficient” bridge is one with some maintenance concerns that do not pose a safety risk. A “deficient” bridge typically requires maintenance and repair and eventual rehabilitation or replacement to address deficiencies. To remain open to traffic, structurally deficient bridges are often posted with reduced weight limits that restrict the gross weight of vehicles using the bridges. If unsafe conditions are identified during a physical inspection, the structure must be closed.
     
    What is a “functionally obsolete” bridge? A functionally obsolete bridge is one that was built to standards that are not used today. These bridges are not automatically rated as structurally deficient, nor are they inherently unsafe. Functionally obsolete bridges are those that do not have adequate lane widths, shoulder widths, or vertical clearances to serve current traffic demand, or those that may be occasionally flooded.
