Between Two Shovels Ep.11: Matt Smeltzer (El Dorado County) - The Mosquito Road Bridge Project

Matt Smeltzer, Deputy Director of Engineering for El Dorado County, takes us inside the largest capital improvement project in county history: the $20+ million Mosquito Road Bridge that crosses a 400-foot canyon.This isn't your typical bridge project. For nearly 30 years, Matt has been working to replace a century-old swinging bridge that emergency vehicles couldn't even cross. The new bridge will eliminate a dangerous 1.3-mile journey through rockslide-prone canyon roads, replacing it with a safe 0.3-mile crossing 400 feet above the American River.From helicopter-delivered geotech equipment to portable concrete batch plants, this project showcases the incredible logistics behind modern infrastructure. Matt shares the persistence required to secure 100% federal funding and the engineering challenges of building 200-foot tall columns in one of California's most remote locations.Key Timestamps:0:00 - Introduction 4:59 - The big bridge story begins8:46 - Project timeline: 1998 to 202614:43 - Helicopter geotech and construction challenges18:11 - Balanced segmental cantilever construction explained21:06 - Timeline delays and complexity factors26:43 - Bridge aesthetics and design features28:46 - Why this bridge matters: saving lives and moneySubscribe for more infrastructure insights from California's transportation leaders.Learn more about Connector JPA: https://connectorjpa.comGuest: Matt Smeltzer - Deputy Director of Engineering at County of El Dorado
