What's Going On At Lexington/Trapelo Intersection?

You may have seen it recently -- the steel building girders being erected at the corner of Lexington Street and Trapelo Road and wondered what is being built there.

Well, only half of an answer is available yet. According to Waltham's Acting Building Inspector Patrick Powell, developer and site owner Daniel Yu is constructing a building to eventually house retail and office tenants. However, Powell said no tenants have applied for the site yet. 

City Councilor Robert Logan tweeted that it would be the same building Yu had planned for  Those plans were eventually cancelled.
