Shiny new borked infrastructure in Burlington

Burlington (Massachusetts) or perhaps Nordblom (owner of a good-sized office park in Burlington) has been upgrading some of their roads. Overall, I cannot complain, it is better for me than riding on the Middlesex Turnpike (which is a terrible road; no crosswalks, insultingly incomplete sidewalks, crap in the road, and rumpled pavement).

But, at a shiny new rotary, with shiny new granite curbs and correctly painted crosswalks and yield teeth, they botched the accessible crosswalk:

It’s about a 4-inch step, where it should be flush instead. Maybe there’s more asphalt coming? Or maybe the asphalt will be raised later, in a crosswalk hump? Both sides have the step, so it seems to not be an accident.
