First-of-its-kind, self-cleaning pedestrian bridge swings into place
This week, the main span of the FIU-Sweetwater University City Bridge was lifted from its temporary supports, rotated 90 degrees across an eight-lane thoroughfare, and lowered into its permanent position.
The largest pedestrian bridge moved via self-propelled modular transportation in US history, it is also the first in the world to be constructed entirely from self-cleaning concrete.
When exposed to sunlight, the titanium dioxide in the concrete captures pollutants and turns them bright white, reducing maintenance costs.
Construction of the $14.2 million, 32-foot-wide bridge began in the Spring of 2017 and is expected to be completed in early 2019. When it is finished, the bridge will be 289 feet long and 109 feet tall.
As well as connecting plazas and walkways, the bridge will serve as a study and gathering space for the university students.
