RE: Blackmore Bend Development/East Main Traffic Impact Study
Dr.Woolard,
Since we had our meeting with the City of Bozeman to discuss the Traffic Impact Study(TIS)for
the Blackmore Bend Development,we have had two meetings with MDT to discuss the TIS and
recommended improvements to both E. Main St. and Highland Blvd. MDT reviewed our
conceptual design and has provided some direction regarding their desires for access and
adjacent street improvements.
Based on a December 7, 2016 email from Jean Riley, our MDT Project Manager, the MDT staff is
agreeable to the modifications we have proposed as described below:
• East Main Street(N-50)—The proposed modification is to remove the raised median to
the west of Haggerty Lane. The center turn lane will be a two-way left turn lane to the
approach into the development from E. Main Street, then the turn lane will be a
dedicated left turn lane for Highland Avenue.
• Highland Avenue (U-1215)—The proposed modification is to add an additional
dedicated left turn lane from Highland to E. Main Street. This will require modification
to the signal at Highland/E. Main, adding an additional lane on Highland, and relocating
the asphalt sidewalk on the west side of Highland Blvd. The signal and intersection will
be modified accordingly.
MDT has also provided the following requirements pertaining to the proposed design:
• The intersection of Highland and E. Main must be as close to perpendicular as
possible. In the conceptual plan it is skewed, consistent with how it currently
exists. This will not be allowed.
• The transition point on the turn-bay must be a curve transition not a point as shown on
the plans.
• The right-of-way necessary to modify Highland and the asphalt sidewalk should be in
MDT's name for the length of the turn-bays.

We concur with MDT's desire and requirements as noted and we have revised our conceptual
layout(included as Sheet C01 in the Master Site Plan Application). Based on these revisions,
MDT has stated that submittal of a revised TIS is not necessary. We request the City's written
concurrence to proceed on this basis.
