April 5, 2019
This week, crews finished the following:
- Placed the footing for the new Davis Brook Regulator Structure.
- Excavated below the train rail at Front and Railroad Streets, and installed 60' of 60"-diameter, 1"-thick protective steel casing with 42"-diameter PVC sewer pipe inside the casing. This work was done on Saturday from 5am to 9pm with Pan Am Railways signalmen looking on. The casing/sewer was laid 12' deep. The excavation beneath the tracks was filled with low-strength concrete "flow-able" fill. Two 4" conduits were also laid in the rail crossing with the casing for future electrical or communication use.
- New 42" sewer was laid 100' up Railroad Street and the second of five 8"-diameter precast sewer manholes was set and connected to new sewer in the street. Next week, new sewer will be laid and it will turn off the street right-of-way and into grass area between Railroad Street and the concert venue.

- Set 8' diameter base for Sewer Manhole 1 and made concrete collar for connection to box culvert.
- Set first two pieces of 42" diameter PVC sewer and 20' of ductile iron casing for railroad crossing.
Crews plan to make railroad crossing on Saturday, March 30. Crews will close Railroad Street for vehicle traffic on Saturday, March 30. Next week, crews will install 42" diameter sewer, and tie reinforcement steel for regulator structure walls.
Week of March 25 - March 29, 2019
This past week, S.E. MacMillan received three significant deliveries: a pre-cast eight-foot diameter manhole from American Concrete in Veazie; a load of reinforcement steel from HarMac Rebar and Steel, Fryeburg, Maine; and two 18-foot pieces of 42-inch diameter ductile iron pipe from McWane Ductile, Birmingham, Alabama.
In the coming week, MacMillan plans to set SMH 001 near the intersection of Front and Railroad Streets and connect it to the 8'x9' box culvert with 42-inch ductile iron pipe. They also expect to complete tying reinforcement steel and then placing the concrete for the Davis Brook Regulator Structure footing slab.
Week of March 18 - March 22, 2019
S.E. MacMillan will complete excavation for construction of the Davis Brook regulator structure early in the week. CES Inc. of Brewer will have a survey crew on site Monday to lay out the corners of the regulator structure. On Monday, the City of Bangor Sewer department will do a pre-construction inspection of the inside of the 9'x8' Davis Brook box culvert. MacMillan has a concrete coring company from New Hampshire scheduled to be on site Wednesday to make a 48" core into the box culvert as access for a new 42" sewer. The Sewer department's pre-construction inspection will verify the internal condition of the culvert. Forming of the regulator's concrete base slab may begin at the end of the week.
Week of March 11 - March 15, 2019
Work to include continued excavation, installing construction fencing, and building a crushed stone construction driveway entrance on Railroad Street. There will also be a construction entrance built on Dutton Street for access to the old Maine Central Railroad roundhouse site where MacMillan is hauling and will temporarily stockpile excavation. MacMillan is tentatively scheduled to work with Pan Am Railways the weekend of March 30-31 to excavate beneath their railway track and install the five-foot diameter steel casing for new sewer and communication conduit crossing.
March 7, 2019
Work started on the City's Stone Sewer Replacement and new Davis Brook Regulator Structure sewer project on Thursday, March 7. The S.E. MacMillan Company of Bangor, Maine has started excavation for the new Davis Brook regulator structure.
February 11, 2019
On February 11, 2019, the Bangor City Council awarded the contract for the Stone Sewer Replacement and New Davis Brook Regulator Structure Project to the S.E. Macmillan Company of Bangor, Maine. There were four bidders for the project and S.E. MacMillan’s bid of $2.55 million was the low bid. As part of the City’s Consent Decree with the EPA and the DEP, the project is designed to reduce the number of combined sewer overflows on the Davis Brook section of Bangor’s west side sewer system. Major components of the work include:
Construction of a new underground Davis Brook Sewer regulator structure.
Pipe jacking a 5’ diameter steel casing beneath the railroad tracks on Railroad Street.
Laying 420 feet of new 42” PVC sewer pipe to connect the new regulator structure to the existing 8’x9’ box culvert Davis Brook storage tank.
Removing the existing Davis Brook Regulator Structure, abandoning approximately three hundred forty feet of 6’x7’ stone sewer overflow and lay 6’ diameter RCP and 6’x7’ precast box culvert to replace the overflow sewer.
The work will be undertaken on Railroad Street and in the grass area between Main Street, Railroad Street, the gated drive entrance to Darling’s Waterfront Pavilion, and the northeast Pavilion pedestrian gate. The Contractor will begin moving equipment and material to the site this month and excavation is anticipated to begin in early March. The project has a substantial completion date of December 1, 2019. The contract requires the Contractor to coordinate construction work around current and future scheduled Waterfront events.

Safety Improvements at Broadway, Earle Avenue, and I-95 Ramp
An informational meeting was held in Council Chambers at City Hall on September 27, 2018 at 6:00pm to discuss safety concerns on a portion of Broadway (Route 15) from the intersection of Center Street and the I-95 Northbound ramps to the intersection of Broadway and the I-95 Southbound ramps.
This section of Broadway was identified within the 2015 Broadway Corridor Study (see below) as experiencing a higher-than-average number of accidents and heavy congestion during weekday commuting periods. The Maine Department of Transportation has funded a project to further evaluate this portion of Broadway and design safety improvements to address the high number of crashes and vehicle congestion on this segment of Broadway. The City of Bangor selected Gorrill Palmer Consulting Engineers, Inc. to provide traffic evaluation and design services for this project. This was the second public meeting for this project.
The purpose of this meeting was to review proposed conceptual safety improvement plans with the public and address any questions and concerns they may have. Representatives of the City of Bangor Engineering Department and engineers from Gorrill Palmer were present at the meeting. You can watch video of the meeting here.
If you have any questions or would like further information concerning this project, please feel free to contact John Theriault, Bangor City Engineer, at (207) 992-4249.

Broadway Corridor Study
The objective of the Broadway Corridor Study is to develop a Traffic System Management Plan to ensure that the following will allow Broadway to operate at an acceptable level of service through 2025:
(1) Preserve existing roadway capacity over the long term to facilitate through traffic movements and minimize congestion, while at the same time providing safe vehicular access to new and existing developments along Broadway; and
(2) Maintain the functional integrity and safety of the corridor, while accommodating the public and private needs for access to adjacent land parcels. In developing the plan, the consultant will utilize accepted engineering standards to address such items as:
- The frequency and spacing of intersecting streets and private driveways;
- The location, spacing, timing and coordination (for progressive two-way traffic flow) of existing and future traffic signals; the location and design of turning lanes;
- Channelization, or other turning movement controls;
- Identification of current levels of service and development of access management standards (which may include minimum sight distance requirements, corner clearance requirements, separation standards, etc)

Exit 186 Intersection
Click here to view the report from MDOT regarding the left turn on Stillwater Ave. at Exit 186
Below is a summary of recommended changes from the report:
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 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.
