PROJECT: I-81/SR-34 Interchange - Exit 4 - Jefferson Co., TN
CLIENT: Tennessee Department of Transportation
Vaughn & Melton was contracted by the Tennessee Department of Transportation to perform design services for the I-81/SR-341 interchange design. SR-341 was upgraded to four traffic lanes with a continuous turn lane. Vaughn & Melton was responsible for the redesign of the interchange including grades, drainage, erosion protection and phasing of construction under traffic.
The SR-341 typical curb and gutter section was extended through the I-81 interchange at White Pine. The existing deficient structures for I-81 were replaced with two 3-lane bridges elevated 3-feet above the profile. Special consideration was given to the maintenance of traffic on I-81, SR-341, and the ramps during construction. The final project cost was approximately $17 million.
