I- 40 Crosstown Expressway Realignment Project
The project—the largest ever undertaken by
Oklahoma DOT—consists of realigning 4.5 miles
of interstate highway through Oklahoma City.
The new 10-lane interstate will be constructed
along an existing railroad corridor 2000 feet
south of the existing interstate. A boulevard will
be constructed on the existing interstate alignment
that will provide the primary access into downtown Oklahoma City and the Bricktown entertainment district.
In this project, the Oklahoma DOT obtained
design files through its consultant partners. Its
information consisted of 2D design layouts, with
the exception of the digital terrain model. Using
this information made it possible for the agency to
construct a 3D environment using MicroStation.
More than one user could work in many of the different design files, thanks to MicroStation refer-
ence files. For example, one could work on the
retaining wall while another was placing vehicles
on the highway.
The Oklahoma DOT relied on InRoads’ horizontal
and vertical control, template construction, and
surface utilities to make the task of creating the 3D
environment much easier. The structure of InRoads
tab and tree display provided a controllable plat-
form for managing the many alignments and sur-
faces, as well as locating and managing the fea-
tures needed for the complex design. ;

The U.S. project involves an environmental impact
statement and preliminary design for the construction of a new urban arterial roadway. The road is
3.1 miles in length and construction costs are
about $50 million.
for use by pedestrians and bicyclists, a park-way/boulevard median, and side-slope landscaping. Visual presentation of proposed project
photo-simulations was key to gaining public support for the project.
The road includes two lanes in each direction,
with paved outside shoulders and landscaped
shoulders where the directional roadways
diverge. All alternatives include a multi-use path
A draft environmental impact statement was devel-
oped and public comments have been received. ;
