Concord's downtown underwent a significant renovation between 2015 and 2016, during the city's "Complete Streets Improvement Project". At a proposed cost of $12 million, the project promised to deliver on categories of maintenance to aging infrastructure, improved accessibility, increased sustainability, a safer experience for walkers, bikers and motorists alike, and to stimulate economic growth in an increasingly idle downtown. The main infrastructural change was reducing the four-lane street (two in each direction) to two lanes plus a turning lane in the center. The freed-up space would contribute to extra width for bikes to ride in either direction, increased curb size and an added median where there is no need for a turning lane. Concord opted to add shared lane markings for bikes, rather than a dedicated protected bike lane.
