MODESTO – Caltrans and the city of Modesto broke ground today on a $61 million project that will relieve traffic congestion on Pelandale Avenue at State Route 99 and create an attractive new gateway to showcase the city.

"The benefits this project will bring to Modesto are significant. Commuters will benefit from less traffic congestion, and the project will help boost the local economy by making it easier to travel to and from the city’s regional shopping center and industrial parks,” said Caltrans Director Malcolm Dougherty.

The number of lanes on the overcrossing will double from three to six; new ramps will connect SR-99 with Sisk Road and Salida Boulevard instead of busy Pelandale Avenue. As a result, motorists will spend less time stuck in traffic burning up gasoline, which will save time and money and improve air quality. Additional auxiliary and merge lanes will be part of the interchange, giving motorists more time to safely merge and exit.

Motorists entering the city from the north on the highway will view a sculptured overcrossing with the greeting, “Welcome to Modesto, Water, Wealth, Contentment, Health,” carved into the rock wall.

The project is funded by nearly $44 million from Proposition 1B, a 2006 voter-approved transportation bond, and $17 million from local and regional funds. More than $17 billion in Proposition 1B funds have been put to work statewide for transportation purposes – and savings from those projects are being used to build the Pelandale interchange.
Caltrans, the city of Modesto, the Stanislaus County of Governments, and Stanislaus County worked together to secure funding for the project.

“This project is monumental for Modesto,” said Mayor Garrad Marsh. “This is the north gateway into our community and it will soon become a beacon to travelers along Highway 99. Not only will safety be improved and traffic congestion eased, but the welcoming signage will be the crown-jewel of this project, giving Modesto the name recognition it deserves along the highway – an invitation to visitors and a welcome home for residents.”

The existing interchange was built in 1970, and Modesto’s population has more than tripled from 62,000 to 200,000 in the last 45 years. An average of 110,000 vehicles travel along SR-99 at Pelandale Avenue daily, a figure that is projected to top 180,000 vehicles by 2035.

“This project is an excellent investment of taxpayer dollars. It will be a real asset for commuters, businesses, and the agricultural industry that all rely on Highway 99,” said Caltrans District 10 Acting Director Amarjeet Benipal.
