The 2018 construction season is already under way in Minot, with work beginning on initial phases of flood control work and the second year of work beginning on the Broadway Bridge project, among other projects.
The City of Minot has introduced a new Geographic Information System that will allow users to find detailed information about construction projects, road closures, and load restrictions. The new site can be found at minotnd.maps.arcgis.com/home/index.html.
Phases 1-3 of flood control
Work is under way on the first three phases of the Mouse River Enhanced Flood Protection Project. Phase MI-1 Fourth Avenue includes six blocks of, floodwalls, a new sanitary sewer lift station, and a large storm water pump station, and the relocation of several blocks of Fourth Avenue Northeast between Broadway and Third Street Northeast. Phase MI-2 Napa Valley runs from the Highway 83 Bypass to 16th Street SW and includes levees, a road closure structure, and two storm water pump stations. Phase MI-3 Forest Road will create protection on the north side of the river between 16th Street SW and the end of Third Avenue SW and includes primarily earthen levees. All three phases require numerous water, sewer and storm sewer relocations, along with relocation of the NAWS water line. The total cost for Phases MI-1, MI-2 and MI-3 is estimated to be $99.4 million. Construction is scheduled to be completed in 2020. The funding on these three phases includes 65 percent coming the state and 35 percent from City funds. The primary source for local funding is from a portion of the Minot city sales tax allocated to flood protection.
U.S. 83 Broadway Bridge Viaduct Replacement
Work on the second year of replacing the two Broadway Bridges began April 2; the project is scheduled to be finished in late fall 2018. Traffic will be moved to the two north-bound lanes and will have head-to-head traffic during the removal of the old bridge on the west side, and the reconstruction of the new west side bridge. Lunda Construction is the general contractor for the project. The estimated construction cost of $20.8 million. The Federal Highway Administration is funding nearly 80% of the project, with the remaining cost covered by the state of North Dakota and the City of Minot.
U.S. 83 Bypass
Additional lanes have been built on the west side of the current lanes. The $13.5 million project includes the DOT and the City of Minot. The project includes adding traffic signals at the intersection of the Bypass and 21st Avenue NW. The intersection has been realigned, improving access to the apartments located west of the Bypass and providing improved access to the Bypass. Work began in 2017 on creating the new driving lanes, as well as the construction of two new bridges. Work in 2018 will begin soon, and includes finishing the driving surface of the new lanes, and replacement of the existing northbound river bridge. Once the new west side lanes are completed, head-to-head traffic will be diverted onto those lanes while work takes place on the east side lanes.
North Hill water tank
This project will provide 1.5 million gallons of water storage for the North Hill system. This will provide required fire flows for Erik Ramstad Middle School as well as storage for future expansion and fire flow demands. Construction began in 2017, and is expected to be completed by fall 2018. Cost of this project is $3,336,000.
Sundre water line relocation
Work is expected to be completed mid-summer on this $13.5 million project that will relocate a water line from the Sundre well field that carries two-thirds of Minot’s municipal raw water that gets treated for the residents of Minot and surrounding communities. The project includes constructing a new 2 million gallon storage reservoir and a booster pump station near the Sundre well field southeast of Minot, and installing miles of new pipeline that will bring raw water from the aquifer to the Minot Water Treatment Plant. The new booster pump station will push the water from the new storage reservoir through a new 24-inch pipe to a location approximately 4 miles south of Minot near 93rd Avenue Southeast, where it will tie into the existing raw water line for the Northwest Area Water Supply project. From there, the water will be sent northeast for approximately 7.2 miles into the City of Minot Water Treatment Plant. The project is expected to cost $13.5 million, with 65% of the cost being paid for by the State Water Commission. The City of Minot is paying for the project up front, and then the City will get an equal amount of credit from the State Water Commission on future water projects, including flood control.
Water Treatment Plant expansion
A $26 million expansion project that will essentially double the daily capacity at Minot’s Water Treatment Plant is set to begin this spring. The project is part of the Northwest Area Water Supply Project, which will provide clean drinking water to many communities in northwest and north central North Dakota. The $26 million project is funded between the North Dakota State Water Commission (65%) and the City of Minot (35%). The City’s portion of the funding was collected through Minot’s 1-cent sales tax. The original Minot Water Treatment plant was built in 1951, and has undergone several expansions and renovations. In 1951, the plant could treat 6 million gallons of water per day. By 1961, renovations and additions boosted the plant’s daily production to 18 million gallons per day. The plant currently treats between 13 million and 14 million gallons of water per day. The prime contractor on the expansion project is PKG of Fargo. Sealed bids for the project were opened in late December. The project is expected to take approximately two years to complete.
Upsizing sanitary sewer lines at lagoon
This project is expected to begin this spring, depending on the weather. The nearly $6 million project will upsize the sanitary sewer lines that convey water from the aeration pond to the lagoon cells. Under peak flow conditions, the current pipes aren’t large enough. The project is expected to be finished by end of 2018. The general contractor is Wagner Construction.
