Project Location: The project is located along the Wapsipinicon River and associated wetlands in Section 14/15, Township 81 North, Range 1 East, Clinton County, Iowa, approximately 2,450-feet southeast of the intersection of 235th Street and 142nd Avenue near the town of Wheatland.

Project Description: The project includes the removal and replacement of an existing railroad bridge across the Wapsipinicon River at Milepost 33.31 on the Clinton Subdivision in Clinton County, Iowa. The proposed replacement bridge will occupy the same footprint as the existing bridge. Dimensions of the new structure will be approximately 376.5-feet in length by 36-feet in width. Temporary bridges will be constructed to the north and south of the existing bridge for construction equipment access and will be removed upon project completion. An existing roadway off of US Highway 30 will be used. Tree trimming/removal may be needed along this road. Equipment/material staging will be located in a fallow agricultural field located to the southwest of the bridge. Construction of the new bridge will include temporary cofferdams, grading, and the installation of two new piers as support structures. Impacts from this project include approximately 0.098-acres of permanent stream impact from pier construction. Permanent impacts to adjacent wetlands will include 2.74-total acres. Approximately 2.4-acres of forested wetland will be converted to emergent wetland during construction activities, while 0.34-acres of forested wetland will be permanently affected by fill material. Temporary impacts to additional emergent, scrub-shrub, and forested wetlands will include approximately 4.05-acres. These disturbed areas will be returned to pre-construction conditions.
