Following the public meeting in July 2018, the design team made changes to the project to incorporate feedback, limit impacts, and reduce costs.

To reduce excavation efforts, the design now calls for independent alignments and grades for US-95 NB and SB, Vintage 95, and Mineral Ridge Road. The shared use path and utility corridor are now located adjacent to Mineral Ridge Road.

ITD will build a retaining wall along Mineral Ridge Road to protect the existing wetland (Dry Lake) and concrete dissipator. (A dissipator prevents erosion where stormwater pipes or ditches discharge into areas such as slopes or channel banks.)
