A $3 billion, 235-mile project aims to connect a trio of coastal cities in southeast Florida.

An old Chicago station serving 1.8 million subway and bus riders each year is soon to receive a $15 million makeover.

With a billowing, veil-like facade and generous skylights, a large new transportation hub in San Francisco will replace a shabby station from the 1930s.

Nearly 90 years after it was first proposed, a 2-mile stretch of subway connects Manhattan’s Upper East Side to Midtown.
