Abstract

The proposed project is a bridge replacement on State Route SR 90 over the CSX Railroad about 8 miles southeast of the City of Ideal. The project begins approximately 2,405 feet southeast and ends approximately 2,895 feet northwest of the proposed bridge for a total project length of approximately 5,300 feet (1.0 mile).

The proposed bridge would be constructed approximately 75 feet, centerline to centerline, southeast of the existing bridge. During construction, traffic would be maintained on the existing SR 90 alignment Upon completion of the new bridge, traffic would be moved to the new bridge and the existing bridge would be removed.

The existing SR 90 consists of two l 2-foot travel lanes with 4-foot to 6-foot grassed shoulders within variable ROW between I 00 feet and 230 feet in width. The posted speed limit is 55 miles per hour (mph). The proposed SR 90 typical section would consist of two 12-foot travel lanes with 8-foot shoulders (2 feet paved and 6 feet grassed). Additional ROW up to approximately 122 feet in width would be required on the south side of SR 90. Additional ROW up to approximately 15 feet would be required on the north side of SR 90 within 310 feet of the eastern terminus and within 200 feet of the western terminus. The maximum total of ROW width would be approximately 305 feet. Permanent easements up to 35 feet in width on the south side of SR 90 and up to 25 feet on the north side of SR 90 would also be required. Temporary driveway easements a maximum of 35 feet in width would be required on both sides of SR 90.
