Chicago Department of Transportation Comm. Gia Biagi speaks during a news conference announcing the “Chicago Works” capital plan on Monday.

Chicago will nearly double its typical roster of street makeovers and spend hundreds of millions in additional dollars on bridge replacements, building renovations and technology upgrades by the end of next year, city leaders announced Monday.

Flanked by a handful of key aldermen and agency heads, Mayor Lori Lightfoot held a news conference to detail the first steps of “Chicago Works,” the five-year infrastructure program getting underway this spring. Funded by General Obligation bonds issued by the city last year, the $3.7 billion program aims to catch the city up on decades’ worth of deferred maintenance on streets and other city-owned assets.
