Carlsbad to add a second rail line, begin construction [Video]

SAN DIEGO — A major project is underway right now to add a second rail track in Carlsbad to help alleviate congestion in the area.

The ultimate goal is to replace the aging Batiquitos bridge with a new double track one.

But before construction can begin, SANDAG needs to ensure they’re protecting certain species that live in the water below.

On Friday, they sent members of their management construction team into the lagoon equipped with an inflatable boat, sonar equipment and diving gear.

It’s not the type of work most people think of when it comes to building a new bridge.

But, in this case, it’s crucial.

“For in lagoon work, we want to be extra extra safe,” said Tim Pesce, a senior environmental planner with SANDAG.

Pesce said divers are looking for two specific species.
