38 TABLE B3-1A TYPES OF OS/OW PERMITS AND PERMIT ISSUING AGENCIES (United States) State Level Do Other Agencies Jurisdiction Types of OS/OW Permits Issued by State Level Jurisdiction Issue OS/OW Permits? Type 1--Overweight permit (passed screening). Vehicles are screened by analyzing them for a certain subset of bridges. If they pass this screening, then a permit is issued as appropriate. There is no specified AL weight limit used to define these types of vehicles. These vehicles typically have standard gage axles. Type 2--Overweight permit (failed screening). Vehicles that do not pass the screening described in Type 1 or that have non-standard gage axles (except for cranes) are passed to ALDOT's Bridge Rating office for detailed analysis. Type 1--Single oversize trip permit--These permits are issued to vehicles that do not conform with the dimensions given in 17 AAC 25.012. The vehicle is not overweight. Single trip oversize permits are valid for three days to five days. No new load rating is required. Type 2--Single overweight trip permit--These permits are issued to vehicles that do not conform with the weights given in 17 AAC 25.013. The vehicle is not oversize. Single trip overweight permits are valid for three days to five days. A review of the load rating may be required. AK Type 3--Single trip oversize/overweight permits--These permits are issued to vehicles that do not conform with either 17 AAC 25.012 or 17 AAC 25.013. Single trip oversize permits are valid for three days to five days. A review of the load rating may be required. Type 4--Extended trip permits--These permits are issued for different periods of time. They are issued for a minimum of one month and a maximum of 12 months. The permitted vehicle may make unlimited moves while the permit is valid. No Type 1--Type A.

Permittees are given a color-coded Route Capacity Map of Idaho state highways. Colors are determined based on the limiting bridge capacity for that segment. Also, allowable axle and axle configuration loads are given. Annual permitted trucks must obey the load restrictions of the Route Capacity Map for all state highways they travel. ID Type 2--Single trip permits--May be issued to vehicles carrying nondivisible loads that do not have annual permits or weigh in excess of 200 kips.

TABLE C3-1B TYPES OF OS/OW PERMITS AND PERMIT ISSUING AGENCIES (CANADA) Do Other Agencies Jurisdiction Types of OS/OW Permits Issued Issue OS/OW Permits? 1. Multi-trip overweight permit--This type of permit can be issued to units with permanently mounted equipment and to vehicles carrying construction equipment. The permit is valid point to point within the province. There are axle and gross weight caps in the permits that have been pre-determined as acceptable for travel across non-restricted bridges structures. The permits are not valid for crossing restricted bridges. This permit is normally issued for a year and there are no limits to the number of trips. 2. Single trip overweight--This type of permit is issued for a single trip overweight. When this permit is issued, every bridge structure along the route is reviewed by comparing the default capacity of each bridge against the vehicle weight being permitted. If the bridge capacities are adequate, the permit is issued with no further review. If a bridge structure has inadequate capacity, then the bridge is re-rated with the actual weights and dimensions of the vehicle being permitted to see if Alberta it has adequate capacity. No Type 1--Annual trip permit. This is used primarily for those smaller vehicles; i.e., mobile cranes or trucks hauling small construction equipment from site to site within the city limits. Calgary Type 2--Specific trip permit. This is used for the balance of the overload requests. Any request would require that the route be considered and those bridges that require additional evaluation identifed. These bridges would then be reviewed to see whether they are suitable for the proposed load. No Permits issued by Department of New Type 1--Single trip permits--review existing load ratings.

An annual permit will be issued to a specific tractor for either overmass and/or overdimension. A Newfoundland single annual permit will be issued for various trailer configurations. Single trip permits are issued when the dimensions exceed the annual permit limitation. The maximum dimensions are: width 3.66 m; height 4.5 m; front or rear overhang 3.1 m; length--up to and including 25 m; Government of Newfoundland and mass 64,000 kg.

Permit vehicles with GVW falling within the "maximum observed load level (MOL)," which is assumed as the GVW per Ontario Bridge Formula + 10,000 kg. These vehicles are allowed to travel without any travel restrictions and no load rating is required for bridges. Typically, these vehicles are covered by all three types of permits mentioned above. 2. Heavy permit vehicles may be allowed to travel under certain travel restrictions; e.g., reduced speed, sole vehicle when travelling on bridges, etc. Load rating of bridges for these cases is still not needed. 3. Extra heavy vehicles that fail to meet the weight limits associated with category (2) will need a full evaluation of bridges along the Municipalities also issue permits for travel route.

For towing trucks hauling damaged trucks (seldom used--no review needed). 5. For overweight vehicles carrying an indivisible load that roughly exceeds the legal loads for a specific axle configuration by less than 15%. These permits are usually annual permits but they can also be given for a specific route and for a limited duration (generally no review needed). We have a special posting for these vehicles that specifically prohibits access to a bridge by these vehicles. The bridge is posted that way for two reasons: (a) It is a bridge that has been designed with a loading that is prior to the H20-S16 loading and that has not been rated yet. (b) It is a bridge that has been rated for legal loads but that is not considered to have the sufficient reserve (resistance) to allow a Class 5 vehicle loading. 6. Special travel permits for overweight vehicles that do not meet the conditions for a Class 5 permit or the legal loads because of a weight problem or a configuration that is not included in the allowed configurations. These are controlled permits as defined by the CAN/CSA-S60-00 Canadian Highway Bridge Design Code. 7. Oversize vehicles require an expert's report from the MTQ (no review needed regarding bridge rating), but an important field Quebec mobilization to verify the vehicle access to all bridges on the route.

CT DE DC It is extremely difficult, for various reasons (tracking of multi-trips, loads applied for are often higher than the real ones, etc.), to relate bridge deterioration to bridge loading and FL frequency of loading. Until we introduce some consistency among the state to perform evaluations with the explicit goals of maximizing mobility while agreeing on preservation strategies, we are bound to have inconsistencies in permitting decisions. GA HI ID If there is to be uniformity in allowing permit loads between the states, then each state's IL laws regulating permits must be uniform with the other states. It is NOT an engineering issue, it is a legislative issue. IN We use the superload routing system, and thus our electronic data in the most efficient manner. The system analyzes every bridge along a given route for a given permit truck configuration. The process eliminates the need for special knowledge about bridges on a route and saves time previously spent reviewing a route by hand and trying to determine IA which bridges are the critical structures to analyze. A permit can be reviewed and approved/rejected in minutes instead of hours or days. Having all states provide this type of fast turnaround on permit requests would be the best improvement to OS/OW carrier industry. Uniformity in the rating procedures between states will not have a significant affect on the trucking industry. KS KY LA ME MD MA MI 105

106 TABLE C5-1A (continued) State/ Jurisdiction Aware of Any Relevant Studies/Investigations? Additional Comments How does your state rate curved steel or post-tensioned concrete box structures? We are just starting to use MDX for rating curved steel. For longer span bridges do you consider any lane loading or is permit-only vehicle in lane? We are contemplating this. Does your state have any rating trucks that are used in design check? We do not have any. How many permits are processed by bridge rating staff? We do about eight/day. When you give speed restriction do you eliminate impact in check? We lower impact to 5% rather than what is calculated. What load maximum triggers a bridge check in permit office? In Minnesota, if load is above 145 k then bridge office sees permit. Do you use the new MN LRFD steel distribution factors for LFD rating check? They are less conservative and allow heavier permit loads. Are any states finding any problems with newly designed LRFD bridges with LFD ratings? For LRFD the M in steel is lower than LFD, thus causing lower ratings. For states using Virtis are they checking shear on older prestressed concrete bridges? This seems to drastically lower rating yet no evidence of problems in field. For finite-element software (such as MDX), what do you put in adjacent lanes when checking permit truck? We put HS20 truck in adjacent lane(s) in combination with permit truck. MS MO MT NE NV Contact for clarifications. NH NJ NM Uniformity of overloads in Southwest--one meeting held March 2005, Las Vegas, NV. NY It is going to be very difficult to get consistency from state to state permit reviews for a variety of reasons, including posting policy, state laws for legal loads, rating methods that are used, no confidence in AASHTO Rating Specifications where the real world does not fit the specification results (e.g., Rating of Reinforced Concrete Members), shear control NC ratings in specifications (there has never been a known shear failure in NC). Results from most research or synthesis is for the highest quality structure where cost is not an issue (these study results should be based on the smallest structure where cost is a major factor in making decisions as to what will be done). An agency cannot afford to spend precious dollars on elaborate studies or work for permit studies for small bridges. ND 1. Ohio bridge definition is any structure with total 10 ft or larger. 2.
