Dear Mr. Powell:
In reference to the proposed Belt Line Road improvements submitted to
this office by Ginn Inc., we have reviewed the plans and offer the
following comments.
The improvements planned are reconstructing the existing 2 lanes to a
six lane urban section, and transitioning to an existing 2-lane bridge
at Belt Line Road and I.H. 635. This bridge will be submitted to be on
the 10-Year Project Development and Control Plan. The bridge has approval
requested by resolution from local municipalities including Dallas County,
City of Coppell and City of Irving. The bridge was constructed in 1979,
part of I.H. 635 construction, and is in very good condition. Therefore,
total replacement of the bridge is not an attractive alternative.
Due to increased traffic demands and the need to provide six continuous
lanes over the bridge, it will need to be widened.
In a meeting with Schrickel, Rollins & Association, City of Irving, City
of Coppell, Ginn Inc., and SDHPT on February 4, 1986 in this office we
discussed the widening of the bridge. It was pointed out by Mr. Van
McElroy, Bridge Engineer for SDHPT, the bridge would have to be widened
to the west due to vertical clearances.
The future bridge design will be determined at a later date with several
factors detemining the ultimate bridge width. Factors included would be
median width, left turn lanes, shoulders, sidewalks, etc. Widening of the
bridge will require additional right-of-way to be needed on the west side.
The mount of right-of-way required would be related to the future bridge
width. A reverse curve would need to be in the transition zone to match
your proposed section with the future widening. However, if your alignment
was shifted to the west it would lessen the severity of a reverse curve.
