Section 4: Freeway MainlanesAnchor: #i1004235
Purpose and Functional Criteria
Freeways are intended to provide a very high degree of mobility. Accordingly, freeway mainlanes provide no direct access to property and access to the freeway mainlanes is provided only at interchanges and ramps. The spacing of interchanges and ramps needs to allow entering and exiting vehicles to weave safely and to provide adequate acceleration/deceleration.
The design of freeways is governed by the TxDOT Roadway Design Manual, Chapter 3.
