GARDNER- BRIDGE REPLACEMENT, G-01-023, TRAVERS STREET OVER TRAVERS POND OUTLET
The scope of work for the replacement of the Travers Street Bridge includes the complete replacement of the superstructure and substructure of the existing single span steel stringer bridge, which was constructed in 1938. The new bridge will be a single span separated pre-stressed concrete box beam superstructure supported by new semi-integral reinforced concrete gravity abutments to be located in back of the existing abutments, and founded on bedrock. The work includes the reconstruction of the roadway approaches as necessary to provide a 28.5 foot curb to curb roadway width and a new 6.0 foot wide sidewalk on the westerly side of the bridge. The bridge rails shall be standard “Texas” rail. The bridge profile grade will be established based on the results of a Hydraulic Report which will establish the adequacy of the waterway opening. A Geotechnical Report will also be prepared to verify the suitability of the selected foundation and substructure type, and a Bridge Type Study Report will be prepared to evaluate the overall cost effectiveness and general suitability of the proposed design, in comparison with several other bridge types. During the construction, the road will be closed to through traffic, and a posted detour will be implemented.
