A Transportation Environmental Study Report (TESR) will be prepared for a 30-day public comment period toward the end of the study. The TESR will describe the site selection process, evaluation and selection of the Technically Preferred Alternative (TPA), the Preliminary Design of the TPA, and recommended mitigation measures.
