How exactly is "Better Naito" better?

How exactly is

In response to the seasonal “Better Naito” project that closes one lane of northbound vehicle traffic on Naito Parkway for a protected bike lane, the Alliance sent a letter to Portland City Council urging reconsideration of the project, particularly given the significant number of construction projects in the central city this year that are impacting travel. The letter shares the experiences of employers and employees who report significant congestion south of the lane closure and impacts to the downtown street grid, and questions reducing the capacity of a key north/south route through the central city.
