Um....they did just restripe for 2-way traffic and widen a portion of the road by a few feet...more often than not a road is resurfaced when these activities occur....for example, when they added a lane in each direction of I-10 (at the new Cecil Commerce Pkwy) they also resurfaced the existing lanes.
btw....this entire project, which includes all the new mast arm signals, new sidewalks, and the resurfacing/restriping cost around $3 million....that's pretty good for a one mile (+/-) stretch, especially when you consider that mas arms like that often cost $100,000 each!
