Spring load restrictions are now in effect in SD Spring load restrictions went into effect Feb. 25 on all state highways that lie in the following areas:
* In western South Dakota, weight restrictions will be implemented on all highways east of SD 73, north of US 212, and west of the Missouri River, excluding SD 73 and US 212;
* In the Black Hills area, weight restrictions will be implemented on all highways south and west of I-90 from the Wyoming state line to Rapid City, west of SD 79 from Rapid City to the junction of US 18, and north of US 18 to the Wyoming state line, excluding I-90, SD 79 and US 18;
* In eastern South Dakota, weight restrictions will be implemented on all highways east of the Missouri River.
Except for SD 20 in the Timber Lake area, all highways in the above described areas will be posted as shown on the 2000 Spring Load Restriction Map. SD 20 from Timber Lake to US 12 will be posted at 7 tons per axle and not 6 tons per axle as shown on the map.
Due to mild winter conditions, many highways in the western area of the state will not be posted as shown on the 2000 Spring Load Restriction Map.
Also effective on Feb. 25, only limited overweight permits will be issued for the movement of non-divisible loads in those areas of the state that are under spring load restrictions. The overweight permit limitations are as follows:
* The weight per axle may not exceed that allowed by the South Dakota Spring Load Restriction Map or addendum Spring Load Restriction Reports;
* The maximum weight per axle shall be limited to the smallest of 20,000 pounds per axle or 450 pounds per inch width of tire; and
* The weight may not exceed that allowed by the South Dakota Bridge Weight Limit Map or other overweight permit issuance criteria provided by the DOT.
The effective date of load restrictions is determined by weather and road conditions. Normal overweight permits will continue to be issued in that portion of the state that is not under spring load restrictions.
