SR 520 Bridge Replacement and HOV Program - Construction cameras

Montlake Project 

We have four mounted construction cameras that take pictures every 10 minutes, day and night, of our SR 520 construction work in the Montlake area of Seattle. The arrows at the bottom of the display screen allow you to move back and forth in time. Cameras 3 and 4 also offer time-lapse viewing by pressing the play button at the bottom center of the screen.

You can view archived photos of past construction activity at completed SR 520 project sites by clicking on the location links below.
