Drivers take note: A new traffic light is now partially operational. 

The new traffic lights under construction at the intersection of Old Westport Road and Chase Road are now running, but are not yet fully operational. 

According to Dartmouth police, the lights have been set to a flashing pattern, and will be in that mode for about the next week.  

It is in preparation for the completion of the $677,646 Massachusetts Department of Transportation project to bring a full set of traffic lights to the intersection. 

In addition to the lights, the project also funded necessary paving, drainage, and other improvements in order to accommodate the traffic lights and turning lanes. The project also added new sidewalks and shoulders for cyclists. 

It is one of the busiest — and most dangerous — intersections south of Route 6. A 2012 Southeastern Regional Planning & Economic Development District study identified eight crashes from 2008 to 2010, and found that during peak commuting hours, traffic reached near-breakdown levels. 

The full project is anticipated to be completed by the end of the summer, according to MassDOT.
