Project Description
Morgan County Bridge Replacement and Road Realignment
The Morgan County Engineering Department contacted our engineers about a total bridge replacement of Bridge Number 443 over Mans Fork and the realignment of County Road 20. The existing bridge had experienced a reasonable amount of damage over the course of many years and was no longer able to support legal loads. This project included the replacement of the substructure and superstructure. The proposed superstructure is composed of adjacent pre-stressed concrete box beams and the substructure consists of a concrete capped pile abutment
Our engineers conducted a roadway realignment study and prepared construction plans for the new alignment and grading in accordance with the provisions of the American Association of State Highway and Transportation Officials, “LRFD Bridge Design Specifications” using the HL-93 live load, and the guidelines for “Geometric Design of Very Low-Volume Local Roads.” Our team also executed a hydraulic study to determine if any flood issues resulted from the final span length of the bridge and a load rating on the superstructure.
All plans for the bridge were prepared to conform to the requirements for ODOT administered LBR bridge plans. The finals plans were then submitted to ODOT, District 10 Office for Phase 1, 2 and 3 Review and comment. Additionally, ODOT received and reviewed our engineers’ Right of Way plans and Legal Descriptions that were certified and approved by the County Engineer.
