Sec. 29-204. - Penalty upon conviction.
Sec. 29-203. - Bridge weight limit violation.
It shall be unlawful for the operator of any vehicle to drive, haul, push or tow, wholly or partially, any load upon a posted weight limited bridge, which collectively exceeds the officially designated and posted maximum bridge weight, whether or not all load bearing wheels travels onto the bridge.
(Ord. No. 93319, § 1, 1-25-01)
Sec. 29-204. - Penalty upon conviction.
This is not a traffic ordinance authorized under the Texas Motor Vehicle Statutes, and is not governed by the penal provisions there under. Any violation of the provisions of this division is hereby declared to be a health and safety related misdemeanor, and upon conviction is punishable by a fine of not more than five hundred dollars ($500.00).

Formula:
Percent Loss of Pavement Life = 0.0039 × (PCI/206.963)
Read the Percent Loss of Pavement Life on the left side of the figure. Round the value to the nearest whole number. Table of PCI values in increments of five (5) follows and shall be used as a guide:
| PCI | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 | 60 | 65 | 70 | 75 | 80 | 85 | 90 | 95 | 100 |
| PLL Value | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 2.30 | 4.47 | 8.19 | 14.30 | 23.96 | 38.73 | 60.70 | 92.58 | 100.00 | 100.00 | 100.00 |
PCI > 85 use 100% Loss of Pavement Life
PCI ≤ 50 use 0% Loss of Pavement Life
Pavement Cost per Square Yard Rate is scheduled as follows:
| Classification | Cost per Square Yard (FY 2000-2001) |
| Thin (flexible pavement) |
$32 |
| Medium (flexible pavement) |
$38 |
| Thick (flexible pavement) |
$42 |
| The cost per square yard rates shall be updated annually. | |
To determine pavement classification you must first determine the pavement equivalent granular thickness (EGT). The EGT value is equal to the sum of all the layers in the existing pavement section times the respective value for each material as follows:
| Pavement Material | EGT Value per Inch |
| Lime Stabilized Subgrade | 0.6 |
| Crushed Limestone Base | 1.0 |
| HMACP, Type A or B | 2.0 |
| HMACP, Type C or D | 1.8 |
| Asphalt Stabilized Base | 1.7 |
| Ashpalt In-Place Base Stabilization | 1.6 |
| Old or Weathered Concrete |
2.0 |
| Newly or Mildly Weathered Concrete | 3.0 |
EGT value = SUM (EGT value per inch × inches of material in the section)
Note: The pavement cross-sectional thickness (in inches) can be determined from one of the following sources:
(1) City of San Antonio's Pavement Management System
(2) Field investigation through coring or excavation of sample sections, or
(3) From the as-built drawings on file in the city engineer's office.
Then, determine the pavement classification as follows:
| Total EGT Value | Classification |
| Less than or equal to 15 |
Thin (flexible pavement) |
| Greater than 15 but less than 20 | Medium (flexible pavement) |
| Equal to or greater than 20 | Thick (flexible pavement) |
Use the pavement classification to determine pavement cost per square yard rate.
