“When the cash-strapped Massachusetts Turnpike Authority doused the lights on the Zakim Bridge last week, it crushed a lot of spirits, not least those of Miguel Rosales. The architect, who designed the bridge with a skirt of regal blue lights to evoke the shimmering Charles River, … mailed a check for $15,000 to the authority – enough to light the bridge for three months – and urged the agency to, please, let the lights shine again, for the sake of the city.” The authority’s response? It’s not enough.
