 The city of New Haven has begun work on a $2.6 million project to improve the traffic flow on Quinnipiac Avenue. It'll include new pavement, raised crosswalks and intersections, speed tables and sidewalks. Officials say the goal is to keep drivers from speeding and to make pedestrians safer. Sunshine today, afternoon showers, thunderstorms possible, low to mid-90s, heat index values pushing up to near 100 degrees for the next day or so.
