PROJECT OVERVIEW
This project, funded partly by the DCED/CFA Multimodal Transportation Fund (MTF) Grant, is the construction of a new on ramp from SR 4026 to westbound SR 0422. This includes pavement of the proposed on-ramp, construction of concrete mountable curb, installation of guiderail along the new on ramp, and replacement of an overhead sign mast arm and pole. This work also includes the elimination of the existing left turn movement from SR 4026 onto westbound SR 0422 by closing the gap in the existing concrete mountable median and removing the channelized roadway and island on the existing westbound ramp.
