CSX Bridge Replacement at Tanyard Creek

The substructure replacement of the CSX bridge over Tanyard Creek consisted of installing eight steel pipe pile foundations with rock sockets, four precast bent caps, and two retaining walls.

To reach the bridge location, the project team constructed site access through the middle of a crowded City of Atlanta park. Temporary work platforms were built on the rail embankment to allow the drill rig to be lifted via crane onto the platforms to drill rock sockets and set pipe pile. The substructure portion of the bridge allowed us to turn the bridge over to CSX to begin setting superstructure spans.

The location of the project was a large hurdle for the project team. The community park is situated in the heart of Buckhead, a major suburb of Atlanta. The park is a 14.5 acre park that is one of the only remaining preserved sites of the historic Battle of Peachtree Creek. There are historic markers noting the prominence of the site around Tanyard Creek Park. The park features a large playground, large open fields on the west side, and acres of wooded areas with hiking trails. The park is connected to several parks throughout the city by the Northside Trail to the Beltline. The nearby neighborhoods include Collier Hills and Atlanta Memorial Park. The construction required access roads for equipment and disruption of park use for the neighboring communities. The project team reached out to the neighboring home owner associations and offered frequent site tours and community involvement meetings to make sure they were aware of the construction progress and to answer any questions.

Brasfield & Gorrie worked with the owner throughout the project to work around the active rail line without delaying the project schedule. CSX did allow track outages for the installation of the Bent Caps. Our partnership with CSX allowed us to weave in value engineering to save time on certain portions of the construction and allow for more time around the active rail line.
