The state is opening the LaSalle Parking Garage on North Third Street to the public, a move that will add 300 more spaces for people who are visiting downtown Baton Rouge.

The garage will officially open to the public on Monday. It will be cash-only, but an ATM is being installed in the structure at 617 North Third. Parking fees will start at $2 for less than one hour and go up to $10 for four to 24 hours.

Parts of the garage are being used by the LaSalle state office building, the downtown YMCA, the Hampton Inn and tenants in the IBM Building. But Davis Rhorer, executive director of the Downtown Development District, said there are enough unused spaces for people who are headed to downtown restaurants, bars or attractions.

“This is almost like getting a whole new garage at Third and Main streets,” Rhorer said. He thanked state officials for opening up the unused spaces in the garage to the public.

Opening up the garage allows the state to generate additional revenue and provide needed parking for downtown, said Stafford Palmieri, commissioner of administration, which has oversight for state buildings.
