Kurt and Nancy Lorenz were ecstatic to get a quick tour Tuesday inside the historic Bridgeport Covered Bridge before contractors descend on it this week with engineers, architects, machinery, I-beams and cables. “It’s great to get back in it and smell it,” said Kurt Lorenz, adding that he and his wife are longtime Nevada County residents, Bridgeport Bridge-lovers and members of the San Juan Ridge Citizens League and the San Juan Ridge Taxpayers Association.
