Take Hwy 146 across the bridge and veer right onto 146 Business. This bridge is best seen from the parking area of the Bridgewater Events reception hall.
This bridge is located in the middle of an industrial complex - lots of oil and chemical refineries. So, during the day it's pretty drab, but at night, with the bridge lights and the chemical and refinery facilities lighting, it's a lovely sight.
The Fred Hartman Bridge at night, as seen from the Bridgewater Events reception hall, where I was photographing a wedding reception.
