| The Legacy Parkway -
Awarded to the joint venture team of Carter + Burgess, Horrocks Engineers and H.W. Lochner,
the Legacy Parkway will be a four-lane, limited access, divided highway extending approximately
14 miles from I-215 at 2100 North in North Salt Lake northward to the junction of I-15 and U.S.
Highway 89 near Farmington. A multiple-use trail for pedestrians, bicyclists, and equestrians will
parallel the Parkway, which is being designed to blend cohesively with the built and natural environments
through which it passes. The Horrocks Engineering team was responsible for the roadway design of Segment #3
(Glovers Lane to I-15 and US-89); the design of all Structures along the corridor; and right-of-way engineering,
utilities coordination, and surveying for the entire project. The Legacy Parkway project presented a whole new
arena for structures design. Several bridges were redesigned in order to fit with the new layout and scope of the
project. However, several bridges from the original design/build project were retained in the interchange areas
in order to use existing materials. Using the existing design build metric plan sets and tying the new roadway
design into the profiles presented a series of challenges. In order to achieve a balance of form and beauty, the
structures within the Legacy Parkway corridor were designed with a variety of aesthetic treatments. These treatments
added to the travel experience of both pedestrians, who use the trail that parallels the parkway and motorists on the
parkway. The completed project consisted of 3 segments, 22 bridges, 11 culverts, multiple drainage headwalls, multiple
timber boardwalks, and more than 55 retaining walls.
