Caltrans preps overhaul of Highway 99 in Fresno. Here’s what will change.

Two key exits on Highway 99 will be shuttered, but an expansion of the highway to eight lanes is on the horizon.

Major changes are coming to Highway 99 in southwest Fresno, including more lanes and pedestrian bridges. 

The changes were approved by the Fresno City Council on Thursday. 


Driving the news: The council approved an agreement with Caltrans for the State Route 99, El Dorado to Clinton Rehabilitation project. 

  • The agreement was approved on a 6-0 vote by the council with no discussion. Councilmember Mike Karbassi was absent. 

The big picture: The project will replace much of the existing asphalt covering the lanes from El Dorado St. in the south to Clinton Ave. in the north – a total of 3.2 miles of road. 

  • The current asphalt has been there for more than 50 years, making those lanes costly to repair. 
  • Thursday’s agreement will not cost the city any more money. Caltrans has already secured the $400 million necessary to complete the project. 
  • Caltrans expects construction to run from late 2024 to early 2029. 

Go deeper: Along with bringing the lanes up to date with long-lasting concrete pavement, the project will add auxiliary lanes and make it possible to expand the highway in that section to eight lanes in the future. 

  • A new interchange will be constructed at Olive Ave. that will have roundabouts on each side of the freeway to connect the entrance and exit ramps. 
  • Caltrans will remove the entrance and exit ramps at McKinley Ave. and Belmont Ave. without replacing them. 
  • The project will see four overcrossing bridges at El Dorado, the railroad, Belmont and Olive be replaced. Three undercrossing bridges at Nielsen and McKinley will be replaced, and the Teilman/Pacific overcrossing bridge will be removed. 
  • A Roeding Park sound wall will also be installed that will be decorated with art of zoo animals.
