Historical Development of IH 35 (1.1 MB)
The purpose of this display was to give the history of both traffic numbers and original construction dates for the entire 94-mile IH 35 corridor. Bell County information was displayed in Blue text. Falls and McLennan County information was displayed in green text and Hill County information in black text.

The historical and projected average daily traffic numbers were presented in a boxed table from left to right across the display. For example, Salado information is given at the far left of the display. Beginning in 1950, the average number of vehicles using the IH 35 corridor was 3,400. This number has increased to 40,000 by the year 2000. The projection for the year 2025 is an average of 81,000 vehicles. This was consistent across the corridor and can be seen from a historical basis. Every 20 years, average daily traffic numbers have doubled on the IH 35 corridor. Texas Department of Transportation is projecting those numbers to again double overall by the year 2025.

Also, from left to right, the history of when the original corridor was constructed is shown on this display. The color of text also corresponds to the county. For example, on the left side of the display in blue text is a section of the corridor from Williamson County Line to Belton, which was constructed between 1955 and 1960. The Interstate Project Office, in its initial round of public meetings, tried to make a point in their presentation that a majority of the corridor is approaching 50 years in age, well past it's original design life. Regardless of the planned expansion to the corridor, the existing facility is in need of design upgrades to today's freeway standards. This re-design and reconstruction of the existing 4-lane facility alone would require a need for additional right-of-way.
