INTRODUCTION PURPOSE OF STUDY TEC, Inc. has been retained by the Town of Westford, Massachusetts to prepare roadway and traffic improvement plans for Groton Road (Route 40) in the vicinity of the intersection of Groton Road / Dunstable Road in Westford, Massachusetts. The proposed improvements are needed to address existing safety and operational deficiencies regarding the intersection geometry, conflicting turning movements, multi-modal accommodations, and delays. The Northern Middlesex Council of Governments (NMCOG), under Contract with the Massachusetts Highway Department (now the Massachusetts Department of Transportation [MassDOT]), previously completed a Route 40 Traffic Study1 in 2005, which examined traffic congestion and safety issues along the corridor to guide the Town of Westford in planning future growth and development in this area. Since 2005, intersection delays and congestion have increased due to population growth and the construction of various commercial and residential developments. This Functional Design Report (FDR) pertains to the following roadway and intersection improvements in the vicinity of the intersection of Groton Road / Dunstable Road: Installation of a fully-actuated traffic signal at the intersection of Groton Road / Dunstable Road with vehicular, pedestrian and bicycle control; Construction of exclusive left-turn lanes along both the Groton Road eastbound and westbound approaches at Dunstable Road to accommodate the 95th percentile queues; Realignment of Dunstable Road, south of Groton Road, to provide improved alignment across intersection; 1 Route 40 Traffic Study – Westford, Massachusetts; Northern Middlesex Council of Governments; Lowell, Massachusetts; 2005 T:\T0519\Docs\Various\Dunstable Road\Dunstable Road FDR\T0519.02_Functional Design Report.doc 1 Minor alterations to curb radii to accommodate improved Town of Westford emergency vehicle access and egress through the intersection of Groton Road / Dunstable Road; Minor box widening along Groton Road, within the limits-of-work, to provide a consistent cross-section along the corridor; Construction of a new 2,670-foot asphalt sidewalk along the southerly side of Groton Road, between Crocker Road to the west and the Long Sought-for Pond public access to the east; Construction of a new 235-foot asphalt sidewalk along the westerly side of Dunstable Road, north of the intersection; Installation of new subsurface stormwater drainage infrastructure within the project limits; Striping of new pavement markings and installation of new Manual on Uniform Traffic Control Devices (MUTCD) compliant regulatory and warning signs throughout the project limits; Construction of a new mid-block crosswalk across Groton Road at the reconstructed Long Sought-for Pond parking area; Construction of new Americans with Disabilities Act (ADA) / Architecture Access Board (AAB) accessible curb ramps, where necessary, along Groton Road and Dunstable Road; and A mill and overlay of Groton Road and Dunstable Road within the project limits. This report satisfies the requirements for the 25 percent design process as specified by the MassDOT - Highway Division. Included are a review of existing and future traffic conditions with and without the proposed geometric and traffic signal improvements, a signal warrant analysis, a safety analyses, intersection capacity and queue analyses, and a description of the proposed improvements to the intersection of Groton Road / Dunstable Road. This study examines a 10-year design horizon from the date of the predicted project permitting (year 2027) for future traffic-volume projections and includes an evaluation of the future year conditions without improvements and with improvements. The findings and recommendations for the improvements are based on the detailed traffic impact analyses included in this report. T:\T0519\Docs\Various\Dunstable Road\Dunstable

    MONDAY JULY 19, 2021 By Tréa Lavery Swampscott Conservancy ITEM STAFF SWAMPSCOTT — The Swampscott Conservancy is advocating for a ban on balloons in the town, saying that they have a detrimental effect on the airing out its case environment and on animals that may ingest them. In a post on the Conservancy’s website, President Toni Bandrowicz ac- knowledged that balloons are a bright and fun way of celebrating happy against balloons events, but asked residents to consider the negative impacts as well as the positive. “To protect nature in our neighborhood, perhaps it’s time for Swamp- scott to consider such a by-law — or at least a policy that bans balloons at town-sponsored events, on town-owned properties, or for any events requir- ing town approval,” Bandrowicz said. “The town should promote the use of non-disposable, reusable decorations for such events, not balloons and other single-use plastic decorations.” A handful of communities in Massachusetts have already enacted similar rules, including Chatham, Everett, Nantucket and Provincetown. In 2019, State Representative Sarah Peake of Provincetown introduced a bill that would ban “the sale, distribution and release of any type of balloon, includ- ing, but not limited to, plastic, latex or mylar, lled with any type of lighter BALLOONS, A3 Lynn, Revere and MBTA mapping out transit plan By Allysha Dunnigan ITEM STAFF The Massachusetts Bay Transporta- tion Authority (MBTA) announced its collaboration with municipal partners, including Revere and Lynn, for a series of bus priority projects that will construct up to 4.8 miles of bus lanes — and other pro-transit infrastructure upgrades — to improve bus speed and reliability as the region re-opens from COVID-19-related regulations.

  • Alternatives Analysis Report
    ALTERNATIVES ANALYSIS REPORT Project No. 604694 Intersection Improvements to Gorham Street at Lowell Connector Lowell, MA Prepared for and submitted to: Commonwealth of Massachusetts Department of Transportation 10 Park Plaza, Suite 3170 Boston, MA 02116 Prepared by: CDR Maguire, Inc. 2 Granite Avenue, Suite 150 Milton, MA 02186 March 20, 2017 KEY FINDINGS OF THE STUDY This report summarizes the results of an alternatives analysis study conducted by CDR Maguire to evaluate options for improving safety and traffic operations at the intersection of Gorham Street and the Lowell Connector in Lowell, Massachusetts. Key findings of the study are listed below. • Recommended improvements: 1) Based on a comprehensive evaluation of the intersection geometrics and traffic safety and operational analyses performed as part of this study, a multi-lane roundabout option was determined to be the preferred alternative for the Gorham Street/Lowell Connector intersection (Alternative 4B). The capacity analysis indicates that a roundabout would service traffic with nominal delay (Level of Service A) on all approaches, greatly reducing the existing congestion issues at the intersection. 2) Roadway improvements are recommended for Gorham Street from the Lowell Connector intersection north to just beyond the Gorham Street/Highland Street/Elm Street intersection to accommodate a second northbound travel lane (Alternatives 12 and 23). These roadway improvements would include restriping and minor roadway widening, as well as signal improvements at the northern
