This senior project tasks two groups of students with performing a feasibility study on the improvement of the Beaumont SR-60 corridor. Currently SR-60 is a four lane expressway and the intersection at Jack Rabbit Trail to SR-60 is an at-grade intersection with Westbound Off and On ramps. Caltrans has requested a feasibility study of a lane widening of the corridor to six lanes, an intersection at Jack Rabbit Trail, the conversion of the expressway to controlled access freeway conditions, and frontage roads to maintain access in the community where it was already established. These improvements will take place in order to accommodate for the future growth in the region for the year 2040 with 2020 as the base year.
The team began by deciding our study and design boundaries along with acquiring general information about the area; including a digital terrain map, land use map, right of way map, and many others to obtain a general idea of the area as well as creating a base for AutoCAD drawings. The purpose and needs of the project were deliberated and finalized to be used as a guideline for why and how we would conduct the study. A traffic impact study was conducted along with a Preliminary Environmental Analysis to determine how we could move forward with the geometric design of the project.
