Consideration of Supplemental Agreement No. 3 with HNTB Corporation for design of the Santa Fe, Ridgeview to Mur-Len, Improvements Project, PN 3-C-025-18.
Body
________________________________________________________________________________
Summary:
The Santa Fe Corridor is currently congested, impacting the east-west travel times throughout the city. The interchange is also a critical component of the City’s transportation network, which is also congested and causes traffic to back up onto I-35. The interchange currently has a crash rate that is approximately 6 times the national average.
A Professional Services Agreement with HNTB Corporation (HNTB) was approved by City Council on June 4, 2019, that included traffic analysis, geometric evaluations, and public involvement for improvements to Santa Fe from Ridgeview to Mur-Len. In January 2021, options developed by HNTB to improve the Santa Fe corridor and interchange were presented to Council and in March 2021, a Supplemental Agreement was approved by Council and included preliminary engineering, completion of the environmental process, a detailed analysis of costs associated with the project, and all other items needed to place the city in a position to compete for federal funding for the project. In September 2023, City Council approved Supplemental Agreement No. 2 with HNTB which included moving the project to the field check (60% design) level, identifying and right-of-way needs, beginning utility coordination and continued coordination with KDOT and FHWA. The project is currently at the field check (60% design) level, the environmental work is complete and land acquisition is underway.
This Supplemental Agreement No. 3 with HNTB will allow the project to continue to move forward in design. This Agreement includes professional services supporting land acquisition and utility relocations, preparing the KDOT Traffic Engineering submittal, and progressing design from the field check to the office check (90% design) level. The total cost for Supplemental Agreement No. 3 is $5,354,565.
Land acquisition is currently underway. Utility relocations are expected to begin in late 2025 and continue through 2027. The auxiliary lanes on I-35 are tentatively scheduled to begin construction in late 2026, with Santa Fe corridor/interchange work tentatively scheduled to start in late 2027.
