Montana Department
of Transportation Prepares Projects to Reconstruct Zimmerman Trail
and Construct Roundabout on Montana Highway 3

BILLINGS  The Montana
Department of Transportation (MDT) would like to notify the public
and seek comments on a pair of projects to reconstruct about 1 mile
of Zimmerman Trail and to construct a roundabout at the intersection
of Montana Highway 3 (MT-3) and Zimmerman Trail. The projects begin
at the intersection of Zimmerman Trail and Rimrock Road and extends 1
mile north to the intersection of MT-3. 

Proposed work includes
widening of the roadway where feasible to two 12-foot lanes and
4-foot shoulders, new guardrail and barrier rail, retaining wall,
slope stabilization, new drainage features, upgraded pavement
markings, and improved signage along Zimmerman Trail. The proposed
work also includes improving intersection safety with construction of
a roundabout at the intersection of Zimmerman Trail and MT-3. 

purpose of the project is to improve safety and mobility of the
roadway and extend the service life of Zimmerman Trail from Rimrock
Road to MT-3.

Construction is tentatively planned for 2018 depending
on completion of design and availability of funds. Right-of-way
acquisition is required. Utilities will be relocated during
construction. Construction will require the closure of Zimmerman
Trail to through traffic and a temporary detour will be required on
MT-3 for construction of the roundabout. Construction is expected to
last approximately 3 months.
