The California Department of Transportation (Caltrans) and the Alameda County Transportation Commission (Alameda CTC) are celebrating construction having begun on the State Route 84 (SR-84)/Interstate 680 (I-680) Interchange Improvements project. This $244.1 million project starts south of Ruby Hill Drive on SR-84 to I-680, located within the Tri-Valley.
The SR-84)/ I-680 Interchange Improvements project will enhance safety and accessibility for bicyclists and motorists along SR-84 and at the SR-84/I-680 interchange. Improvements include installing separated striped bicycle paths, modifying ramps, installing two additional miles of express lanes along southbound I-680, tree planting to increase the existing trees three-fold and providing safety for wildlife in the area.
“Completion of this project is made possible by the voters of Alameda County. Alameda County voters supported investments in SR-84 through transportation expenditure plans beginning with the 1986 Measure B, then the 2000 Measure B and more recently with the 2014 Measure BB” said Alameda CTC Executive Director Tess Lengyel. “These investments are critical to improving safety. During peak commute times when SR-84 is congested, collision rates on SR-84 and the I-680 interchange are higher than the state average; this project will change that. Cyclists and drivers will be able to maneuver in and out of driveways and travel more safely on SR-84 and local roads.”
