Overlays (Streets & Roads) – Gold Award

Silver Award – Cannelburg Road, Phase III, Daviess Co., Ind.

Contractor: Milestone Contractors, LP*

Owner:  Daviess County (Indiana) Highway Department   

Engineer: Lochmueller Group

 The Amish population in Daviess County, Ind., is among the highest in the nation.  Cannelberg road was narrow and carried a mix  of semis and other large trucks, passenger vehicles, and horses and buggies.  Traffic  accidents, including fatalities, prompted Daviess County to look for alternatives to improve safety.

This project is the third of three phases to improve CR 900 E from the town of Cannelburg at the south end to Odon at the north end, all three have been constructed by Milestone Contractors.

The design engineer’s solution was to widen the driving lanes and add wide, paved shoulders to be used as buggy lanes.

This project involved the reconstruction of Cannelburg Road with 12 ft. concrete travel lanes with a 1 ft. concrete shoulder and 8 ft. asphalt shoulders on each side for buggies, as well as two 2-ft. gravel shoulders. There was also a realignment at CR 1050 N and CR 1100 N to improve the line of sight and to eliminate any sharp turns.

A key component of any construction project’s success is awareness of and respect for stakeholder needs. The contractor met with the local farmers whose busy farms lined the road, and based on those discussions, modified the construction schedule to accommodate their businesses.  The construction was also phased to help minimize disruptions at intersections and allow for detours around the project.

Although the contract did not prevent the contractor from working on the days during the year considered holy by the Amish, the project team identified those days in conversations with residents and determined they would not to work as a show of respect to the Amish and to allow them to observe the days without interruption.

State Roads – Silver Award

Silver Award – U.S. 6 Reconstruction, Noble County, Ind.

Contractor: Primco Inc.*

Owner:  Indiana Department of Transportation   

Engineer: Beam, Longest & Neff LLC

Shortly after the construction of a new bridge by Norfolk Southern Railroad in Noble County, Ind., Primco was given a 90 calendar day road closure to connect 3,600 feet of 9.5 in. PCCP roadway to the existing road tie-ins and the new bridge.

This was an alternate bid job with concrete winning out after the consideration of life-cycle costs vs. first costs.  The concrete pavement was completed in two 16 ft. passes with a safety edge. Robotic stations were set up at 250 ft. intervals to improve the accuracy of paving and to help impart a smooth ride.

The pavement was finished with a 10 ft. straight edge to double check smoothness with 5 ft. overlapping passes.  Additional steps were taken to  check the edge slump and ensure the best quality pavement. At total of 12,871 SY of concrete was placed at a cost of just over $517,000. The contractor earned more than $85,000 in incentive pay.

State Roads – Gold Award

Gold Award – Route 36 Osborn Curve Reconstruction, DeKalb County, Mo.

Contractor: Emery Sapp & Sons*

Owner/ Engineer: Missouri Department of Transportation            

The Route 36 Osborn Curve Reconstruction project was a high priority project for the Missouri DOT based on the high number of traffic accidents that had occurred over the years due to the curve alignment at the intersection of Highways 36 and 33.

A 3/4-mile section of Highway 36 was completely removed and replaced to change both the horizontal and vertical alignments of the Osborn Curve, as it was known to locals. Both left and right hand turn lanes were added in both Eastbound and Westbound lanes of Highway 36 at the Highway 33 intersection. A total of 2,500 lineal feet of storm pipe along with precast drop inlets were installed to improve drainage through the project along with new signage and pavement marking.

The project consisted of 18,000 SY of existing pavement removal, 25,000 CY of Class A Excavation along with linear grading and compacting in cut to create the new alignment. All of the pavement on the project was PCCP pavement and consisted of 10,000 SY of 8.5 in., 4,500 SY of 7.5 in. and 6,400 SY of concrete A2 shoulder. The existing asphalt pavement was milled, stockpiled and used as aggregate base under the new concrete pavement.

The $1.9 million project was completed and fully open to traffic in only 88 days, and since opening to traffic, has greatly improved safety through this stretch of Highway 36.

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.
