The first five draw span tests are complete and all five were keepers. The east control tower housed engineers, electricians and bridge maintenance staff, all watching the progress intently.
Each cycle brings its own excitement - Lights on, roadway gates down, barrier gates down, center locks up, end locks up, all three lift spans up, draw span engines start, gears move, draw span starts going back (slowly at first and then more quickly), roller guides rumble, control tower floor vibrates, draw span slows and stops, then it all happens again in reverse until one cycle is complete.
Although you can't feel the control tower floor vibrate from your house, you can watch the work on our bridge traffic camera.
The tests are expected to take anywhere from 8-10 hours, but this timeframe is wholly dependent on how things go. If test No. 7, or 12 or 19 raises serious concerns or fails, we're back at square one. Stay tuned!
