Sacramento County  — Caltrans has finished work on a $4.3 million project aimed at easing traffic congestion and increasing motorist safety on State Highway 99 at West Elkhorn Boulevard in the North Natomas area of Sacramento.

The project added auxiliary lanes on northbound and southbound Highway 99 between W. Elkhorn and the Interstate 5 junction. In addition, crews widened the ramps and added new signs and ramp meters. Caltrans plans to activate the ramp meter on the southbound Highway 99 loop on-ramp this fall.

 “The junction of Highway 99 and Interstate 5 often experiences bottlenecks during the peak morning and afternoon commute hours. The new auxiliary lanes greatly improve traffic flow by giving drivers more time to merge in and out of the highway,” said Caltrans District 3 Director Amarjeet S. Benipal.

The new lanes also address anticipated traffic demands from future commercial, industrial and housing developments near Sacramento International Airport and North Natomas in Sacramento.

Caltrans District 3 maintains more than 4,385 lanes miles of state highway in 11 Sacramento Valley and Northern Sierra counties.
