for the first time i got creeped out. this girder is about 30 feet in the air and you can see the tripping hazards. you can tie off on that cable, but it is at your feet and adds to the tripping potential (i did). i almost locked up halfway across. i cannot wait until the effen contractor finishes that walkway. the part you need to walk across is about 25 feet. i didnt stop to measure.....
