Abstract

The South Dakota Department of Transportation (SDDOT) and the Nebraska Department of Roads (NDOR) propose to build a bridge over the Missouri River in the vicinity of Vermillion, South Dakota and Newcastle, Nebraska. (See Figure 1 for a computer image of this proposed bridge.) SO Highway 19, SO Highway 50 and Interstate 29 would connect with Nebraska Highway 12. The Nebraska approach roadway would be designed to provide two 3.6 meter (11.8-foot) driving lanes with 1.8 meter (6-foot) shoulders. The South Dakota inter-connecting roadway will be designed to provide two 3.6 meter (11.8-foot) driving lanes with two 3 meter (10-foot) shoulders for use as bike paths. (See Maps 1 and 2.) The urban section within the City of Vermillion will be designed to provide two 3.6 meter (11.8-foot) driving lanes and a 3.6 meter (11.8-foot) center turning lane.
