CARLSBAD — The Build North Coast Corridor is an ambitious program looking 40 years into the future with a $6 billion price tag
The years-long project ranges from Solana Beach to Carlsbad and is currently in Phase 1, which will cost $846 million, he said. The program is funded through TransNet and state and federal gas taxes.
“There will not be any reduction of lanes during the day,” Kosup said. “Night work, we will try to minimize that and reduce lanes only when traffic allows that.”
Phase 1 started in 2016 and is expected to be completed in 2022.
The highway improvements include Caltrans extending carpool lanes on Interstate 5 from Lomas Santa Fe Drive to State Route 78 in Oceanside. The San Elijo bridge will be replaced, lengthened and additional lanes added, Kosup said.
“This has always been the bottleneck on I-5 going south,” he added. “It will remove the bridge and rail bridge and allow for more lanes going south.”
The next project slated to begin is adding carpool lanes from the San Elijo Lagoon bridge up to Palomar Airport Road. The final stretch from Palomar Airport Road to State Route 78 will not begin for several more years.
Rail improvements include double-tracking at San Elijo and Batiquitos lagoons, while replacing and lengthening the rail bridge over the lagoons. At-grade crossing improvements at Chesterfield Drive in Encinitas are also planned.
The San Elijo Lagoon will also undergo restoration in coordination with the San Elijo Lagoon Conservancy. Some improvements include tidal flushing and beach sand replacement.
Also, a new north-south bike path is part of the project goals.
“A goal is to create a new 27-mile path from UCSD (University of California, San Diego) to Oceanside,” Kosup said. “As we widen I-5, we are able to create those pieces along the way. At San Elijo, you’ll see a hanging bridge that attaches to the freeway bridge.”
Kosup said the goal is for improvements from Manchester Avenue to Palomar Airport Road to begin in October. The project includes 18 miles of new high occupancy vehicles (HOV) lanes on I-5.
Also, five sound walls will be installed in Carlsbad on private property. The project is slated to be completed by late 2021 and cost an estimated $300 million.
‘It’s about 18 months in both phases,” Kosup said of the Palomar project. “The ultimate vision is four additional lanes on I-5. This is only building two additional lanes. There is a second pass, as money becomes available … and that is probably 2035.”
As for the funding, Kosup said the funding “allowed” SANDAG and Caltrans to go up to SR 78 came from Senate Bill 1 funds. SB 1 is the gas tax approved last year by the state legislature adding a $0.12 tax to gas.
However, the bill is under fire from residents and former San Diego City Councilman Carl DeMaio conducted a successful referendum campaign to put SB 1 up for repeal on the November ballot.
“That gas tax increase had a number of competitive programs,” Kosup said. “The I-5 and this particular project did very well in that program. There was one called Solutions for Congested Corridors and is a $1 billion pot. We captured about 20 percent (or $200 million) of that pot.”
The Yes on 6 campaign announced the filing of an ethics complaint with the San Diego County District Attorney’s Office, the California Highway Patrol and the California Fair Political Practices Commission involving workers in Caltrans uniforms that DeMaio said were documented handing out “No on 6” flyers to drivers along State Highway 78.
