A water main broke in Shreveport causing headaches for both property owners and motorists. The break actually caused a wreck, that`s despite barracks set up by city workers. So, that shows you how important it is to figure this problem out. And, that`s just the beginning. Now, a contractor has come out and patched up the busted pipe. However, people along North Market and throughout downtown Shreveport will have to deal with low water pressure at least until later tonight.
