3 A long day without power continues for those who have been blacked out since this morning. We're told ...for some of them ..the power may not be restored until TOMORROW. The transformer is underground on Riverside Avenue ..where workers at the Y-M-C-A first noticed smoke coming from a manhole cover right outside their building. These are pictures J-E-A sent us - showing where the fire was beneath the street. For firefighters to put it out .. J-E-A had to cut 6 circuits .. which knocked out power to about 100 customers .. including the Times Union, and CSX .. and other companies where thousands of employees work. Channel 4's Chris Parenteau has been in Riverside all day and is joining us live.Chris .. who has power back and who doesn't? 3 3 3 3 3 00-0819-2532-37VO JEA says that the underground transformer fire caused extensive damage to one of the circuits that powers areas of Riverside from the Times Union building south to the 5 Points area. It will take crews much longer than expected to fix the damage caused by the fire. SOT Gerri Boyce - JEA Spokeswoman 05:01 We are going to have to replace approximately 250 feet of cable, so we will be working on that through the night. We will have all available crews working on that. Our goal is to have service back on in the morning. But you just don't know what you are going to find during the night. SOT Tom Francis 01:16 We have reports of people who are backed up especially downtown, stuck in lengthy traffic delays. VO With the power out for a big part of the day, many traffic lights in the Downtown and Riverside areas were also out. JSO had officers directing traffic at busier intersections, but dozens of others did not. JEA says they are having to bring up the three circuits without damage carefully. SOT Gerri Boyce 5:59 we won't bring them all on at the same time.It will be one, than another, than another. Correct. We want to do it methodically, to make sure there are no other issues. VO JFRD says they had about 20 firefighters on scene trying to put out the fire this morning. That process took about two hours to put out, but was made much more difficult by it being underground and firefighters not knowing what they might encounter. SOT Tom Francis 01:29 Confined space, by definition is probably the most dangerous situation a firefighter can enter into. To top it all off, when you don't even know what is causing the fire, but you know there are extremely high voltage of power, that kind of scenario is just fraught with danger. 3 If you are having to come down into the area of Riverside Ave, keep in mind that traffic lights will still likely be out until at least tomorrow morning when JEA can get that damaged circuit fixed, so those intersections should be treated as a four way stop. CP CH 4, TLS Chris ..everybody in Jacksonville knows about transformer troubles above ground .. but underground seems so unusual. How rare is something like this?A: One of the JEA workers that was out here told me that the last time he can remember something like this happening was in the 1990's. He says that there can be more damage to the circuits in something like this because the fire is all confined to such a tight space.
