In the past I have photographed the Millennium Bridge here in Denver. However for Day 13, I headed to the newest of the 3 bridges which extends the 16th Street Mall into the Highlands area of Denver.
The Highland Bridge which was completed in December 2006, crosses Interstate 25 providing an easy link from the Highlands to Downtown Denver. While the bridges were built at different times, their look is somewhat consistent with clean modern looks. For this image, I concentrating on the lines flowing through the image as it is a common theme with the bridges.
