REHABILITATION OF A STONE ARCH BRIDGE ON MARYLAND ROUTE 68 OVER ANTIETAM CREEK

The primary objective of the project was to rehabilitate a 163 year old, three span stone arch bridge to retain its usage as a maintainable highway structure. An additional primary objective would therefore be the strengthening of the posted, deteriorated bridge to accommodate current loadings. Secondary conditions were to restore and renovate the bridge so it could replicate its former historical condition. Secondary conditions were to restore and renovate the bridge so it could replicate its former historical condition. Key features of the project included the implementation of an internal reinforced concrete T wall, lightweight concrete fill, anticipated redesign under construction and a partnering charter with the contractor. Many states carry structures on their bridge inventories which are historic in nature and present problems with maintainability to the highway agency. In the past many very old bridges particularly stone arches have been replaced because their deteriorated condition outweighed their historical prominence. With advances in bridge rehabilitation technology, many stone arches can now be strengthened and restored and remain visible parts of the local infrastructure. Also a trend has developed nationwide where the public has a keen interest on the retention of high visibility historic structures.
