and Mt. Auburn Street in the eastbound direction before rejoining Mass Ave east of Putnam Avenue. It then passes by the Massachusetts Institute of Technology (MIT). It intersects the junction of US 3 and Route 3 at Memorial Drive before crossing the Harvard Bridge (also known as the Massachusetts Avenue Bridge) and crossing into Boston, ending at Route 2 and Commonwealth Avenue. Signage mistakes In 2013, Route 2A signs were extended further into Boston through the Back Bay and South End neighborhoods along Massachusetts Avenue. This extension connected it with several additional numbered routes including the Massachusetts Turnpike (I-90) by its junction with Boylston Street, Huntington Avenue (Route 9), Columbus Avenue (Route 28), and Massachusetts Avenue Connector (which connects with I-93/US 1/Route 3 via I-93 Frontage Road) in Roxbury. Not only did neither the Massachusetts Department of Transportation (MassDOT) nor the Boston Transportation Department, acknowledge that Route 2A had been extended, they denied knowing who put up the signs, indicating it was the action of an unknown organization. The Route 2A signs themselves had either wrong directional banners (signed as a north-south highway at least once north of Melnea Cass Boulevard) or are signed backwards (east going west and vice versa), as it heads in a northwesterly direction towards Commonwealth Avenue beyond Tremont Street. On February 26, Boston television station, WFXT-TV aired an investigative reporting segment showing the incorrect signs and their attempt to track down the source. In the report, Boston transportation officials admitted they had paid a private firm, Jacobs Engineering, to manufacture and put up the signs through a wayfinding improvement grant. The signage errors were caused by problems with the plans developed by Jacobs that apparently were not checked for accuracy before they were approved for installation by the city. The city said they were going to take action against the firm to recoup moneys from Jacobs, and would work to fix the signs as soon as possible. Meanwhile, a MassDOT official reiterated that the eastern terminus of Route 2A is at the intersection of Massachusetts and Commonwealth Avenue and that crews would be removing the MA 2A signs further east. In the city's defense, they stated that they do not typically manufacture, install, or maintain signage pertaining to state entities, similar to an arrangement with the Massachusetts Bay Transportation Authority relating to bus stop signage within the city.
