State Route 99 Realignment

Overview

This project will move State Route 99 approximately 100 feet to the west between Clinton Avenue and Ashlan Avenue to make way for the high-speed rail line, which will replace the northbound lanes. Additionally, the alignment project will improve traffic operations, reduce congestion and enhance traffic safety. The project scope includes:

  • Three through lanes with one auxiliary lane for each direction of travel.
  • A reconfigured interchange at Clinton Avenue, which includes replacing the highway crossing at Clinton Avenue. As at Tuolumne Street, the Clinton Avenue Bridge has to be raised to accommodate the future high speed rail trains that will cross underneath.
  • Closure of ramps at Princeton, Shields and Dakota Ave.

Location

From Clinton Avenue to Ashlan Avenue in central Fresno, a distance of about two miles.

Currently

The southbound State Route 99 Clinton Avenue and Golden State Boulevard off-ramps are now open to traffic. Work is continuing on the northbound Clinton Avenue on-ramp, which is scheduled to open when northbound traffic on SR 99 is switched to the new highway alignment in the coming weeks. At the Ashlan Avenue Bridge, crews are continuing to form and subgrade the bent caps for the structure’s abutments. Falsework construction for the new bridge has also begun. A portion of SR 99 is being realigned about 100 feet to the west to make way for the high-speed rail alignment.

Timeline

The SR 99 Realignment project began in December 2015 is expected to continue into the summer of 2018.
