Agenda
1. Update: Construction Projects
(Provided by Jerry Livengood, Andrew Barrowman, and Joshua Saucier)
Bangor Natural Gas completed projects: Bolling Drive from Mitchell to Griffin for a distance of 1300
feet of 2 inch line. Outer Hammond to Pine Grove for a distance of 2140 feet of 2 inch line. Bangor
Housing Authority, Phase 6. Looping 1975 feet of 4 inch from Davis Road to Blue Hill.
Bangor Natural Gas current projects include Mecaw Road from Perry Road to Bangor Tennis Club in
Hampden for a distance of 700 feet of 4 inch line. Leighton Street for 2800 feet of 2 inch line. And
system integrity work on Stillwater Avenue to join two systems to allow for more capacity load on
system for a distance of 2200 feet of 6 inch line starting at Elm Street continuing to Acadia Hospital.
They also noted The Marriott Residence in would place a heavy load on the system and they would be
tie two systems together performing directional boring under Interstate 95. The work would have no
impact on the lanes and was expected to start first week of July.
Jerry noted, anyone interested in having service to be considered in the planning process for
installation on their street should go to the website bangorgas.com to submit their requests.
No Action Necessary
2. Flashing Pedestrian Beacons
(Memo and Map Provided by Public Works Director, Dana Wardwell)
The flashing pedestrian beacons at several downtown locations have been very well received.
Included in the FY 16 Budget are 6 flashing pedestrian beacons. One of these beacons has been
designated to be installed across Main Street at Cross Street when the sidewalk in front of the
Discovery Museum is replaced later this summer. Listed below, in my recommended order of priority,
are 10 locations where the flashing pedestrian beacons may be appropriate. Also included is a map
showing the locations of these crosswalks. Staff is requesting approval of the first five locations for
1
installation of flashing pedestrian beacons or committee suggestions on other locations to install
flashing pedestrian beacons.

Six foot sidewalk for a distance of 3,800 feet. Project Estimate: $863,000.00. City match of
$173,000.00. Construction Estimate to include distant future plans and costs associated with
widening Broadway.

Dana noted that the City is still waiting on funds from prior requests of three years ago.
Moved and seconded for approval with a unanimous vote.
4. Update: Stillwater Avenue, Exit 186 Left Turn
(Materials Provided by City Engineer, John Theriault)
Recommendations
As a result of the analyses completed for the Exit 186 Intersection Study, the following
recommendations are made. Figure 5 highlights these recommendations.
1. Lift the left-turn prohibition on the westbound intersection approach from Exit 186. The
analyses show that this change will have no significant difference in the capacity or level of
service of the intersection. There will be a need to modify the signing, signals, and markings on
this to replace the single through lane with a shared through-left lane.
2. To address the strong pattern of rear-end crashes on the southbound approach to the Exit 186
intersection, the addition of an advance (nearside) traffic signal is recommended to give
southbound traffic an earlier indication of the signal ahead. This could be a pedestal-mounted
signal on the northwest corner of the intersection.
3. On the eastbound (Kohl’s) approach to the Exit 186 intersection, consider restriping and
resigning the four approach lanes to two left-turn lanes, one through lane, and one right-turn
lane. This would convert the left-through lane to a left-turn lane. This change would improve
the balance of volumes in the eastbound approach lanes, providing a modest improvement in
intersection capacity.
4. Link the cross-Stillwater walk phase concurrently to the eastbound vehicular phase to avoid
conflicts between pedestrians and westbound left-turning vehicles.
5. At the Exit 186 intersection, consider improved sidewalk continuity between the west end of the
Stillwater Avenue crosswalk and pedestrian destinations such as the Kohl’s plaza and the
southbound pullover/drop-off space.
6. To increase the width of northbound shoulders for bicycle users between the Drew Lane and Exit
186 intersections, reduce the width of northbound through lanes from 12’ to 11’.
7. To provide northbound shoulders for bicycle users between the Exit 186 and Bangor Mall
intersections, replace the right-most through lane with a northbound shoulder and right-turn
3
pockets located as necessary for the two intersections. The two northbound shoulder
recommendations will provide better shoulder continuity along Stillwater Avenue without
significantly affecting intersection capacity or level of service.
8. Although not evaluated in this study, consider the potential for cycle lengths for signals on
Stillwater Avenue that are shorter than 140 seconds. Long cycle lengths can provide more traffic
capacity than short cycle lengths and help enhance progressive movement through intersections
for some users. However, short cycle lengths can provide shorter delays, shorter queue lengths,
and better levels of service on side-street approaches, and shorter wait times for pedestrians
crossing Stillwater Avenue.
Moved and seconded for approval with a unanimous vote.
Meeting was adjourned.
