Estimated Magnitude: Between $1,000,000 and $5,000,000 Estimated Period of Performance: June 1 - November 15, 2026, and June 1 - July 31, 2027 Project Description The National Park Service is issuing this sources sought as a means of conducting market research to identify parties having an interest in and the resources to support the requirement for construction of Mormon Row Improvements in Grand Teton National Park (GRTE). The project site is the Mormon Row Historic District located east of Moose, WY.

In 2026, construction at Mormon Row will focus on landscape repairs and improvements designed to enhance visitor access, safety, and understanding of this historic site. Work will involve repairing and resurfacing trails and viewing areas to meet ABA accessibility standards, installing clear wayfinding and interpretive signage, and constructing a new off-street parking area for approximately 50 cars on nearly 2 acres. Work will also involve new and improved pedestrian pathways, raised road crosswalk, fencing, vault toilets and site furnishings to better manage visitor access and their activities. All work will be completed with sensitivity to the historic character of the Mormon Row Historic District and in compliance with preservation and environmental standards. Mormon Row Road will remain open to visitors during this construction so work tasks along the nearly mile work corridor must be thoughtfully sequenced to support public access.
