Rhode Island Oversize Permit Cost: Worked Examples

How RIDOT prices a Rhode Island oversize permit, worked through an 11 ft wide excavator, a 140,000 lb transformer and a modular home.

By Haul Handbook editorial team· Updated Oct 4, 2026 · 11 min read

Rhode Island prices a single-trip oversize or overweight permit by gross weight alone, in two flat tiers, and the online portal adds its own small fee on top. A 9 foot wide load and a 14 foot wide load pay the same. What separates a cheap move from an expensive one is the weight tier, the escort count, the rush-hour and holiday blackouts, and the bridges a RIDOT permit does not cover. Every fee this guide works through renders with its source on the Rhode Island oversize and overweight permits page. To compare the same load across states, run it through the oversize permit cost estimator.

How RIDOT prices a single-trip permit

The Rhode Island Department of Transportation (RIDOT) Oversize & Overweight Division issues permits through the RIDOT OSOW Permit Portal, and a reviewer at RIDOT checks every application before it issues. The single-trip charges come in two tiers:

Under 130,000 pounds gross: the statutory fee of $40.00 under sec. 31-25-21(c), plus an enhanced access fee of $4.50 whatever way you pay.
At 130,000 pounds gross or more: RIDOT's rate chart lists $300.00, plus an enhanced access fee of $12.00 on a subscriber account or $20.00 by pay-as-you-go card or eCheck.

The enhanced access fee goes to the portal operator, not to RIDOT. A single-trip permit is valid for five days from the requested start date, and a round trip needs a separate permit for each travel day. There is no per-foot charge for width or length and no per-mile or per-axle weight charge. New Jersey, by contrast, adds a charge for every foot over 14 feet wide, as the New Jersey worked examples show.

One conflict to know about: section 1.4 of 290-RICR-40-00-1 still prints an older, lower trip fee and tells you to apply at the Division of Motor Vehicles in Cranston. The current statute and the online system have replaced both, so price your move from sec. 31-25-21.

You need a permit once a load breaks a legal limit:

Dimension	Legal limit without a permit	Statute
Width	8 ft 6 in (102 inches)	R.I. Gen. Laws 31-25-3
Height	13 ft 6 in (162 inches)	R.I. Gen. Laws 31-25-4
Single vehicle and load	40 ft	R.I. Gen. Laws 31-25-5
Semitrailer	53 ft; over 48 ft 6 in only on the interstate and designated roads	R.I. Gen. Laws 31-25-6
Single axle	22,400 lb	R.I. Gen. Laws 31-25-13
Tandem axles 8 ft apart or less	36,000 lb	R.I. Gen. Laws 31-25-14
Gross weight	80,000 lb under the bridge formula	R.I. Gen. Laws 31-25-14

Scroll sideways to see every column.

The 36,000 pound tandem limit is above the common 34,000 pound figure.

Worked example 1: an 11 foot wide excavator at 95,000 pounds

An excavator on a lowboy measures 11 feet wide, at legal height and length, and grosses 95,000 pounds. It breaks the width and gross weight limits, and it stays in the lower tier.

The permit fee is

$40.00

plus the

$4.50

enhanced access fee, and that is the full charge. If the excavator goes out to a job on Monday and comes back loaded on Friday, those are two travel days, so you buy that stack twice.

At 11 feet wide the load sits under the 12 foot escort line, so the regulation calls for no escort by width. Watch the axles, though: RIDOT's FAQ requires an escort when any axle carries 30,000 pounds or more, so spread the weight before you apply.

Three conditions still shape the trip:

Rush hours. Sec. 31-25-21(f)(1) keeps any load over 8 feet 6 inches wide off freeways and arterial roads from 7:00 to 9:00 a.m. and 3:00 to 7:00 p.m., Monday through Friday.
Bridges. Over 9 feet wide, the owner must arrange with police to halt traffic at one end of a bridge before crossing it, under 290-RICR-40-00-1.
The Washington Bridge. RIDOT lists I-195 East and West over the Washington Bridge in Providence as closed to oversize vehicles and limited to 48 tons (96,000 pounds), anticipated until December 2028. This load is oversize, so plan a route around it.

Worked example 2: a 140,000 pound transformer

A transformer on a multi-axle trailer grosses 140,000 pounds at legal width. That puts it in the upper tier.

The permit is

$300.00

for a load at 130,000 pounds or more. On top of that, the enhanced access fee is

$12.00

on a subscriber account or

$20.00

paying as you go.

That gap is where the account choice matters. A subscriber account costs

$75.00

a year in billing fees, takes 3 to 5 business days to set up, allows up to 10 users, and is invoiced monthly, net 30, by check or ACH only. The lower-tier access fee is the same either way, so the subscriber discount only pays on heavy trips. Divide the annual billing fee by the difference between the two heavy-trip access fees: if you buy more heavy permits a year than that answer, the subscription pays for itself.

The paperwork around this load:

RIDOT approves single-trip permits above 130,000 pounds on application and good cause under sec. 31-25-21(e), so apply early.
At 200,000 pounds or more, RIDOT requires an independent third-party analysis of every structure on the route. This transformer sits below that line.
The weekday rush-hour ban applies to loads over 130,000 pounds just as it does to wide loads.
If any axle carries 30,000 pounds or more, RIDOT's FAQ calls for an escort.

Worked example 3: a 14 foot 9 inch wide modular home section

A modular home section is 14 feet 9 inches wide and 76 feet long, at legal height and under 130,000 pounds. The fee does not change from example 1. You pay

$40.00

plus $4.50.

Here is why this move costs more anyway. Over 14 feet 6 inches wide, 290-RICR-40-00-1 calls for two escorts. Each escort vehicle must:

Be at least compact-car size.
Keep visual and two-way radio contact with the load.
Run flashing yellow lights above its highest point and low-beam headlights at all times.

The travel window is the tightest in the state. 290-RICR-40-00-1 section 1.5.8(B) lets a mobile or modular home over 12 feet wide use I-195, and I-95 from the Massachusetts line to Route 37, only between sunrise and 7:00 a.m. and between 9:00 a.m. and 3:30 p.m. Most permitted moves run from 30 minutes before sunrise to 30 minutes after sunset, with no night travel. The load stays in the right lane wherever two or more lanes are open, and two permitted loads heading the same direction keep at least 1,000 feet apart.

A route over the Newport or Mount Hope bridge adds a permit. RIDOT permits cover state-maintained roads only, so the Newport and Mount Hope bridges need a Rhode Island Bridge Authority permit, and the last stretch on town streets needs a local one.

Blanket and divisible-load permits

Two annual permits replace trip buying for some fleets.

The annual construction-equipment blanket permit costs $400.00 and runs one year from issue. It covers intrastate moves of non-divisible construction equipment, boats or marine assets on company-owned vehicles listed on the permit, within these limits:

55 to 80 feet overall length.
Up to 12 feet 4 inches wide.
Up to 25,000 pounds per axle and 130,000 pounds gross.

It allows day and night travel on state highways under sec. 31-25-21(e), but it needs a flashing amber light above the highest point and red flags on every extremity. It may not cross the Blackstone River Viaduct on I-295 or the Kingston Road bridge on I-95, or pass through lane-width reduction zones. An excavator like the one in example 1 can fit, provided the combination runs 55 to 80 feet and no axle tops 25,000 pounds, so a contractor making regular trips should price the blanket against trip permits. The blanket also carries a per-permit enhanced access fee.

The Annual Divisible Load permit under sec. 31-25-22 is for gravel, sand, liquids, refuse, logs and similar loads above bridge-formula weight. It is overweight only, never oversize, and expires March 31 whatever its issue date. For a Rhode Island-registered vehicle the charge is built into the registration fee, which ties it to your Rhode Island IRP registration and plate weight. Out-of-state vehicles pay by trailer or by weight over the legal limit, as the permits page lists.

Calendar and penalties

Sec. 31-25-21(f)(3) blacks out permit travel around holidays. The dates still ahead in 2026:

Columbus Day weekend: no travel Saturday, October 10, through Monday, October 12, day or night.
Veterans Day: no travel on Wednesday, November 11, or the night before.
Thanksgiving week: no travel Wednesday, November 25, through Sunday, November 29.
Christmas Day: no travel Friday, December 25, or the night before.
New Year's Day: no travel Friday, January 1, 2027, or the night before.

Weekends need a check too. Section 1.5.7 of 290-RICR-40-00-1 says permit travel runs Monday through Friday, while the statute and RIDOT's FAQ list only the holiday blackouts. Read the travel days on the issued permit before you schedule a Saturday.

The fines for running without a permit dwarf the fee:

Over width: $100 per inch (sec. 31-25-3).
Over height: $500 per inch (sec. 31-25-4).
Over length: $200 per foot.
Over axle weight: $125 per 100 pounds.

A carrier caught without a required permit, or over its permit limits, three times in a year loses permit privileges for up to 30 days, and up to 90 days for further violations.

What to check before quoting

Next steps, in order:

Measure the load against the legal limits table and decide whether it needs a permit.
Check gross weight against 130,000 pounds to find the fee tier.
If you buy heavy permits often, compare a subscriber account against pay-as-you-go.
Count escorts by width, length, overhang, height and axle weight, then confirm the count on the issued permit.
Route around the I-195 Washington Bridge if the load is oversize or over 96,000 pounds.
Add Bridge Authority and town permits for any leg off state roads.
Check the move date against the rush-hour ban and the holiday blackouts.

FAQ

How much does a Rhode Island oversize permit cost?

A non-divisible single-trip permit is a flat statutory fee under R.I. Gen. Laws sec. 31-25-21, plus an enhanced access fee kept by the online portal operator. RIDOT's rate chart has two weight tiers: one fee under 130,000 pounds gross and a higher one at 130,000 pounds or more. Width, height and length add nothing to the fee. The permit is good for five days from its start date, and a round trip needs a permit for each travel day. The current figures render with their source on the Rhode Island oversize and overweight permits page.

When does a Rhode Island oversize load need an escort?

Under 290-RICR-40-00-1, a load 12 feet to 14 feet 6 inches wide or 80 to 90 feet long needs one escort, and a load over 14 feet 6 inches wide or over 90 feet long needs two. An overhang of 15 feet or more needs one. RIDOT's FAQ adds an escort for a load over 13 feet 6 inches high or with 30,000 pounds or more on any axle, and a building move needs two escorts plus police from each city or town on the route.

Does a RIDOT permit cover the Newport and Mount Hope bridges?

No. RIDOT permits cover state-maintained roads only. The Mount Hope and Newport bridges need permits from the Rhode Island Bridge Authority, and city or town streets need local permits. RIDOT also lists the I-195 Washington Bridge in Providence as closed to oversize vehicles and limited to 48 tons (96,000 pounds), anticipated until December 2028.
