2021 Construction Projects:
2021 Project Location Map

2021 Bridge Street: Work this week continued on Phase 1 including the completion of watermain relocation and installation of the three large diameter culverts crossing Bridge Street. In addition sand base was imported and is being placed throughout the roadbed.

Work next week will include continued placement of the sand base as well as delivery and placement of the Class 5 aggregate base material. Once the road base is placed and trimmed to the appropriate elevation, concrete paving will commence. The paving is anticipated to take place the week of July 5th and will then need at least two weeks to cure and harden before traffic can drive on it. As paving begins further traffic changes are anticipated as work moves to the next phase.

2021 Truman AvenueNorthland Grading & Excavating started work on sub-cutting and sub-grade preparation for the Phase 1 portion of the project. The 6” Perforated PE Pipe Drain and began installation on Friday. Phase 2 sanitary sewer construction began starting at the intersection of School St. and Truman Ave. where they installed one (1) new sanitary sewer manhole structure. This intersection of School St. and Truman Ave. was closed to traffic so that construction on underground work items at this intersection could be completed. After construction of the new manhole structure at this intersection Northland continued with Phase 2 sanitary sewer construction working southward from School St. towards Phelps St.

Next week: Northland Grading & Excavating plans to continue installation of the 6” Perforated PE Pipe Drain in Phase 1 of the project.  After installation of the Pipe Drain, they plan to start placing the aggregate base layers for the roadway sub-base. In Phase 2 of the project, Northland plans to start water main construction on Monday, starting at the intersection of School St. and Truman Ave. The intersection of School St. and Truman Ave. will remain closed to traffic for work on water main and storm sewer construction to completed. 

Intersections affected:  
Northland will continue working in the Phase 1 portion of the project, from Main St. & Truman Ave. to School St. & Truman Ave. Northland will also be working in the North end of Phase 2 of the project, from School St. to Phelps St. Side-road access across Truman Ave. at the intersections of Agnes St., and Academy St. will be closed to traffic for the duration of Phase 1. Side-road access across Truman Ave. at the intersection of School St. will remain closed until construction of underground work items at this intersection are completed, backfilled, and aggregate sub-base has been placed.  Side-road access across Truman Ave. at all other intersections along the project will continue to be maintained for traffic and residents.  Drivers are encouraged to take alternative routes, if possible, to avoid construction activities on the project.  Residents needing to access the cul-de-sac at the East end of Academy St. may use the temporary access lane in-place at the East end of the cul-de-sac connecting to Main St.  

Overlay Project: The contractor has begun adjusting and replacing manholes on Park St SE & Kast Ave SE. They will continue with Oak View Pl SE and 12th St SE, located west of Lincoln Ave. There will be some curb & gutter replacement and the two catch basins located at 12th St & Lincoln Ave will be removed and replaced.

2021 Street Maintenance: The Crack sealing company has completed that part of the project. The Chip sealing contractor is expected in on Wednesday or Thursday of next week (June 23rd or 24th). That process should only take a day or two for the entire project. They will need the entire street width to lay down the sealcoat, so please be aware of any “No Parking – Street Maintenance” signs. 

Stormwater Management: Storm water is water from rain or melting snow that does not soak into the ground. Instead, it flows from rooftops, across paved areas, and through sloped lawns. As storm water moves across these surfaces, it can pick up and carry along pollutants.

2021 Bridge Street: Work this week continued on Phase 1. During installation of the large diameter culverts that were delivered on-site last week some watermain relocation work was needed and this was completed this week. Installation of the culverts has continued and is anticipated to be completed early next week along with ditch grading and preparation. Work next week will include continued storm culvert installation followed by grading of the road base material.

2021 N Cedar StreetscapeConstruction is set to begin on Monday, June 21st, 2021.
• Construction work will take place Monday–Friday 7:00 a.m.–7:00 p.m. There will be limited times when work must occur outside of this time period, but we will do our best to coordinate and communicate when this is needed.
• Construction will begin with traffic control, detour setup, erosion control, and setting up a temporary watermain.
• Street removals will follow once traffic control is in place.
o Removals will be between Rose Street and Pearl Street while utility installation is completed.
o Partial sidewalk areas will remain in place while the initial work is performed. Safety fencing will be placed alongside the removal limits to separate construction and pedestrian traffic.
• The Contractor may be reaching out to building owners before the construction start date to perform documentation of existing building conditions to ensure no damage to the buildings takes place during construction activities. 
o Vibration monitoring devices will be installed in specific locations to ensure the construction methods are modified as necessary to minimize building vibration.

2021 Truman Avenue: Northland Grading & Excavating finished work on the new storm sewer construction in Phase 1 of the project. Items completed include: removal of existing storm sewer pipe, and installation of new storm sewer main, storm sewer manhole structure, and storm sewer catch basin structures. 

Next Week: The Contractor plans to start sub cutting and the sub grade preparation next week. Items of work planned for next week in Phase 1 of the project include: subgrade preparation, test rolling, and aggregate base.


2021 Street Maintenance: The Crack Sealing crew started on Wednesday (June 9th) and have been working through Friday morning. They have completed all designated streets in the Northeast quadrant of town, and are about half done with their part of the project. On Monday, they will continue crack sealing with several streets in the Northwest, and then Southwest. They should finish by the end of the day Tuesday. 

The Seal Coating contractor is expected to arrive sometime during the week of June 21st. That part of the project should only last several days, except the loose aggregate may not get swept of for another week after that.

Please notice and obey the temporary “No Parking – Street Maintenance” signs where they are placed. They will only need to be there for a day or two.

2021 Bridge Street: Work this week resumed on Phase 1 with some cleanup related to last week’s rain followed by the delivery of the large-diameter storm sewer pipe which is currently being installed near the west end of the project. These reinforced concrete pipes will convey storm water from the industrial park and surrounding areas under West Bridge Street to the south pond and eventually to the Straight River. Work next week will include continued storm pipe installation followed by the hauling of additional road base material. Once the road base is placed and trimmed to the appropriate elevation, concrete paving will commence. The paving is anticipated to take place in approximately two weeks and will then need at least two weeks to cure and harden before traffic can drive on it.
