Morrissey Blvd should just be raised and the bridge should be high enough to let most boats thro. As someone who operated the granite ave bridge and would turn off the radio to the other bridges because of how many requests would come thro for that bridge(some time 2-5 mins apart from each other). Also most boat residents frankly feel cool when they call the bridge to have it opened when a majority of the time it’s their antenna that need to be lowered to fit under… Simply why block traffic to hundred of people at a time for one small marina!
