Located in the rapidly-growing Tri-Valley region of the East Bay, Dublin is located at the crossroads of I-580 and I-680. Dublin is 14.01 square miles in size and currently has an approximate population of 32,550 (and growing!).

Dublin has long been known as the crossroads of the Bay Area. Dublin now sits at the crossroads of two major highways: Interstate 580 and Interstate-680. However, the significance of the "crossroads" dates back over two hundred years when Dublin served as the crossroads of two important stage routes - one from the Bay Area to Stockton and the other from Martinez to San Jose. The Alamilla Spring, located in the Dublin area, provided a place for travelers to change horses and freshen up before continuing their journey.

Dublin has a rich history dating back to 1772 when Pedro Fages led an expedition of 16 mounted men on a journey in search of a land route to Drake's Bay which at that time was called San Francisco Bay. Their return journey brought them through the Amador Valley.

During the past twenty years, the rapidly expanding Tri-Valley area has become renowned as a place of prosperity, a center for internationally acclaimed business parks and home to some of the world's largest corporations.

The City of Dublin, located at the crossroads of the Tri-Valley, has contributed to the planned growth and forward thinking of the area. And the City continues to look ahead to expand and enhance the quality of life for members of the community.
