77th and Broadway Improvements Increase Transportation Safety and Economic Development In Park City

77th and Broadway Roundabout
  • Transportation
  • Park City, Kansas

The City of Park City, Kansas as part of a joint project with the City of Valley Center, Kansas and with assistance from Sedgwick County made an overwhelming impact on community growth, the safety of transportation, and promotion of economic development for both cities and the entire northeast Sedgwick County region by collaborating on the recent addition of a roundabout at the intersection of Ford Street (77th Street) and Broadway.

Ford Street serves as a main access road between Park City and Valley Center as well as to and from I-35 for Valley Center residents. The project encompassed the improvement of an offset intersection, access issues for businesses, and intersection control methods at a dangerous intersection between the two cities.
In 2021, Professional Engineering Consultants (PEC), as city engineer for Valley Center, Kansas designed the intersection improvements. Through a competitive bid, Dondlinger Construction was selected for the construction of the project which started in July of 2021 and finished in late October 2021 in time for the anticipated holiday trucking use of the recently constructed Amazon facility to the south of the intersection. The modification of the intersection to a roundabout has ensured enhanced safety to benefit its users in a
region that has seen recent economic growth.


A unique elliptical design was required for the geometry due to existing utilities that were unable to be relocated, limited right-of-way acquisition, an existing stream crossing directly to the west of the intersection, and an existing detention pond on the northeast corner. Due to the creek crossing on the west side of the intersection and a reinforced concrete box (RCB) structure that was required on the east side of the intersection, a unique grading design was required to hold hydraulic over-topping elevations to the west and grade to match and existing shallow ditch to the east. Design services, utility coordination, and construction efforts were completed on a compressed schedule to ensure the intersection would be
operational in time for delivery truck peak use during the end of year holiday seasons.

The reconstruction of the intersection has strengthened safety with the installation of dedicated free right turn lanes for northbound-to-eastbound and westbound-to-northbound traffic movements. This project provided job creation, retention, and business expansion along Broadway (old Highway 81). This road is used by dozens of companies and thousands of employees and residents daily as a commuter route, and a means to go to and from school or preferred truck delivery route. It also serves surrounding businesses such as 81 Speedway, Hartman Arena, and the Kansas Coliseum.
