about the schematics
schematics found on this site are intended to show the layout
of freeway lanes and the relative location of entrance and exit ramps,
cross streets, access roads, and other important features. Here
are some important notes about the schematics to understand and keep in
- The schematics
are not to scale.
- Lane layouts
are shown for freeway mainlanes, auxiliary lanes, collector/distributor lanes, and ramps. Lane layouts are not shown for
access roads or other roadways due to space limitations, the complexity
of the lane configurations of those roads, and the desire to keep the
clutter on these schematics at a minimum.
- Lanes on most
freeway-to-freeway connectors are truncated to reduce clutter and/or to
fit within a reasonable space.
- Ramps are
shown in their approximate position.
- Except where
especially noteworthy, cross streets are shown as perpendicular to the
freeway and not at the actual angle of intersection, and the freeway is
always shown as straight regardless of any curves or alignment changes.
changes of the access roads on the schematics are done for spacing
purposes and do not necessarily reflect alignment changes of the actual
- Future lane
and ramp layouts are shown for areas currently under construction and
are based on plans available from TxDOT at the time construction
started and may be subject to change.
