The days of peak southbound traffic in the 100 block of North Main Street blocking the Center Street intersection are numbered.The Manteca City Council Tuesday unanimously decreed the much maligned remaining six landscaping bulbs will become history in favor of a redo of the block that has been a tourniquet on traffic flow since the controversial decision in 1992 to ban left turns from southbound Main onto East Yosemite Avenue. That decision was also ultimately reversed.The bulb removal — which are still a ways off due to state-mandated environmental review hoops the city has to jump through as well as changes needed to traffic signals and such — are part of a plan to essentially double the capacity of the block to handle southbound traffic by adding a second lane.When done the block will have:uNo landscaping bulb-outs left. Originally there were eight but two have been removed since they were all installed in 2005 due to them being struck by numerous motorists turning into the Wells Fargo Bank parking lot and pulling out of the alley next to Manteca Bedquarters.uNarrower travel lanes at 10 feet wide compared to the current 12 feet.
