Municipal Streets & Intersections (<30K) - Gold Award

Gold Award –Main Street and Horicon Street Reconstruction, City of Mayville, Wis.

Contractor: Ptaschinski Construction Company*

Owners: Wisconsin Department of Transportation/City of Mayville           

Engineer: Gremmer and Associates


When the City of Mayville reconstructed two major streets, the Ptaschinski Construction Company was able to meet a tight schedule and address other challenges.

Reconstruction involved removing and replacing the existing pavement, base course, sub-base, curb and gutter, storm sewer, sidewalk, and pavement markings.  The contractor was also responsible for replacing permanent signage, street lighting and traffic signals at two intersections.

The typical existing section along the west side of Main Street consisted of a 12 ft. travel lane, a 5 ft. bike lane, a 6 ft. parking lane, a 30 in. curb and gutter with a 5 ft. terrace width, and a 5 ft. sidewalk. The proposed finished typical section along the east side of Main Street consisted of a 12 ft. travel lane, a 4 ft. bike lane, an 18 in. curb and gutter with a varying terrace and a 5 ft. sidewalk.   The intersection of MainStreet and Horicon Avenue was also improved to accommodate large truck turning movements.

The proposed roadway typical section on Horicon Avenue consisted of a 44 ft. roadway with two 12 ft. travel lanes, varying sides for parking, a bike lane that varies to accommodate parking, 5 ft. sidewalks and 30 in. curb and gutter with generally a 5 ft. terrace width.

Access to local residents and businesses during construction an important factor and was handled by using innovative methods to expedite the project.  These included maturity testing for opening strength, voluntary pavement covering, speed dowel headers for colored crosswalks, and partnering with WisDOT to identify and plan staging changes during the entire project to expedite construction.

Scheduling was critical for local access and other details of the project success.  The contractor was very proactive in suggesting staging modifications that increased local access and benefited businesses and their customers. For example, Ptaschinski crew members used two pavers of different widths on one day to expedite the project. The paving crew placed 700 SY of 16 ft.-wide pavement, pulled the first paver off to the side, then continued paving with a 20 ft.-wide machine to complete another 843 SY in the same westbound lane. This rare, mid-day paver change on one continuous pour saved multiple days on the overall project schedule. 

The contractor also successfully constructed a challenging pavement profile that exceeded normal vertical curve requirements.  The contractor worked with project staff to adjust superelevation runoff lengths to improve smoothness on a very flat section that had little margin for error with drainage.  In the end, the team generated excellent goodwill and produced a quality concrete pavement that will serve the City and the traveling public very well.

Municipal Streets & Intersections (<30K) - Silver Award

Silver Award – Mt. Rushmore Road Reconstruction – Phase III, Rapid City, SD

Contractor: Complete Concrete, Inc.*

Owner: South Dakota Department of Transportation

Engineer: Ferber Engineering Company

US Hwy 16, also known as Mt. Rushmore Road within the city limits of Rapid City, is a major arterial route connecting the downtown area with the Black Hills. A three phase project to reconstruct the road that serves as a main passage for many of the 3 million visitors to one of the nation’s iconic landmarks, Mt. Rushmore.

The existing roadway was a five-lane concrete facility with an asphalt overlay. It currently carries an average daily traffic (ADT) of nearly 25,000 vehicles, but ADT is expected to grow to 50,000 by 2039. The new road now consists of two northbound and two southbound lanes with dedicated turn lanes at each intersection. The road also features decorative; colored and stamped concrete medians; colored and patterned retaining walls; colored and stamped sidewalks; and colored ADA ramps at each intersection.

Phase 1 of the project began with the reconstruction of half a major intersection and one block of Mt. Rushmore Road. This phase had a 30 working day window, but was completed in 25 working days, which earned five days of incentive pay.

The remainder of the project was separated into the following phases; phase 2A (southbound lanes, south half), phase 2B (southbound lanes, north half), phase 3A (northbound lanes, south half), phase 3B (northbound lanes, north half) and phase 4 (center medians). Phase 2A through 3B had a 250 working day requirement with phase 4 and overall project completion date of May 18, 2018.

One factor in the success of the project was a series of meetings and ongoing communications among the contractor, the SD DOT, Rapid City officials, subcontractors and utility companies. A dedicated website kept the traveling public and stakeholders updated on all three phases of the corridor reconstruction. Several business and property owners, known at the “Mt. Rushmore Road Group,” met occasionally to exchange ideas with public officials and industry personnel.

The Mt. Rushmore Road project was a success and opened to traffic before the completion date, which resulted in a 26 working day incentive out of a possible 30 working days, which amounted to a $135,000 incentive to the contractor.

A total of 19,200 SY of concrete was placed to create the new 10 in. concrete pavement and aesthetically pleasing center islands, which along with landscaping, now give the traveling public and business owners a much needed, safer, efficient and aesthetically-pleasing road through the heart of Rapid City.

Municipal Streets & Intersections (>30K) – Gold Award

Gold Award – Meridian Boulevard Phase 1

Contractor: Castle Rock Construction Company*

Owner/ Engineer: Douglas County Public Works

Meridian Boulevard in Douglas County, Colo., was built in the early 1980s with a design life of 20 years. After nearly 40 years of service, the road was exhibiting materials-related distress and scheduled for reconstruction.

The section scheduled for reconstruction is directly in front of Dish Network Corporation’s headquarters office, a location that has over 2,000 cars entering and leaving the facility each weekday. In addition to high traffic volume at the construction site, tight space constraints, and requirements to protect existing landscaping, a 90 calendar-day schedule added to the complexity of the project.

A significant amount of subgrade restoration was required in the 0.71-mile project designed to expand the road to four lanes. Soft spots were removed and replaced with recycled concrete road base. 30,100 SY of concrete were placed to complete the 3.51 lane mile project.

Environmentally friendly strategies employed in the project included:

  • The cement was a 10% limestone replacement which lowers the release of carbon monoxide from cement production by 10%, which lowers the carbon footprint; 
  • Use of fly ash, an industrial by-product from coal burning power plants, was used to stabilize the concrete; and
  • Concrete from the original road was crushed and used as road base for the new pavement.

In spite of an early season snow, traffic volume and measures to protect existing landscaping, the project was completed 20 days ahead of schedule and will provide DISH Network employees, visitors and area travelers with a long-lasting roadway capable of handling the rigors of traffic, while also factoring in important environmental considerations.

Municipal Streets & Intersections (>30K) – Silver Award

Silver Award – KY 9 Connector-Roundabouts, Newport, KY

Contractor: Prus Construction*

Owner:  Kentucky Transportation Cabinet             

Engineer: Gresham Smith, Inc.

The construction of the 1.4 mile KY 9 Connector was not just about moving traffic smoothly through the area. The project was essential to economic development in an area where investment was stifled because of high traffic volumes and traffic congestion through residential neighborhoods.

Boasting the first two concrete roundabouts in Kentucky, the project was designed to mitigate the usual stop and start traffic snarls in a busy area. The connector is 10 in. jointed plain concrete with 23 ft. joint spacing.  The main roundabout has a 125-ft radius and is a 40-ft-wide roadway for two lanes of traffic, and the second roundabout has a 105-ft radius with a 40-ft-wide roadway and two lanes of traffic. A total of 42,000 SY of concrete was used in the project.

In addition to the connector and two roundabouts, the project also included concrete sidewalks and bicycle lanes to improve safety for pedestrians and bicyclists. Commuters no longer have to wind through neighborhood streets with a multitude of traffic lights and turns to reach Newport and Newport on the Levee, a large entertainment venue.

Shortly after this project was completed, a $1.5 billion dollar development was announced on a 35-acre site in the area.  The project will be built on a site that been vacant for 13 years.  The new connector, roundabouts and sidewalks not only keeps traffic moving, but also symbolize the vitality and economic hope for this area.

County Roads – Gold Award

Gold Award – County Road 47, Weld County, Colo.

Contractor: Interstate Highway Construction*

Owner/ Engineer: Weld County Division of Engineering   

Reconstruction of Weld County Road 47 was the third and final phase in completion of the County’s Weld County Road 49 Corridor, providing a north-south alternate to 1-25 and US 85, the largest project designed completely in-house by the County.

County Road 47 from County Road 60.5 to State Highway 392 was an existing two-lane, 3.5-mile rural asphalt road with ditches on both sides. Now, the roadway includes four lanes, a continuous 16 ft. general purpose lane, acceleration and deceleration lanes at intersections, a median guardrail and a new irrigation system critical to farmers. More than 167,000 SY of concrete was used to pave 12.89 lane miles at a paving cost of $6.3 million in a project that cost a total of $21.2 million.

The project used a geogrid to mechanically stabilize the subgrade in lieu of the typically specified R-40 subgrade. A new fusion bonded epoxy that fully encapsulates dowel bars was used to provide steel corrosion resistance said to be on par with stainless steel bars. A cure/sealer was used on the concrete to promote sulfate resistance. All concrete aggregates were mined on-site, not only to meet the project demand, but also allow for the continual optimization of the mix design. A non-destructive pavement thickness system was used to determine the concrete thickness without coring into the concrete, thus reducing future maintenance issues.

Public traffic was detoured which allowed for the road to be completely closed for construction – providing a safe construction zone, while expediting the project schedule. Thanks to the hard work and innovative solutions used in this project, this section of County Road 47 reopened five months ahead of schedule.
