The Lowell Connector is slated for several safety upgrades within the year. The Massachusetts Department of Transportation is bidding out one project that will replace worn highway signs with more reflective versions by next spring. The project will also include a stretch of Interstate 495 between Lowell and Haverhill, and will cost about $4.3 million; the Connector section will represent $1.2 million of that cost. A separate project scheduled for summer 2014 will repair and replace street lights along the Connector median at a cost of approximately $2.5 million. Last year, a replacement for the Connector bridge over Plain Street was constructed for $9 million. According to the state Department of Transportation, about 44,000 vehicles travel along the Connector daily.
