Connecticut major traffic generator bonds.
From $100.
A large Connecticut development that draws significant traffic needs an Office of the State Traffic Administration (OSTA) certificate from CTDOT under CGS § 14-311 — and OSTA can require a surety bond guaranteeing the traffic improvements the certificate conditions. Pricing is 0.5% of your bond amount, $100 minimum. Enter the amount OSTA set.

What it is and who needs it.
What the MTG bond actually covers
Connecticut’s Office of the State Traffic Administration (OSTA), within CTDOT, reviews developments that generate large volumes of traffic — typically big retail, commercial, or mixed-use projects. Before such a development opens, it needs an OSTA certificate under CGS § 14-311 confirming its traffic impacts are addressed.
That certificate usually conditions approval on off-site traffic improvements — new signals, turn lanes, signage, or road work to handle the traffic the project will draw. OSTA can require a surety bond guaranteeing those improvements actually get built.
The bond is a completion guarantee running to the State of Connecticut: if the developer doesn’t finish the required improvements, the state can recover against the bond to get them done. The amount is set on the certificate, tied to the improvement cost; pricing is variable and starts from $100, and no credit check up to $100,000.

Claims, renewal, filing, and what sets the price.
If a claim is made
A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.
The surety investigates and pays a valid claim, up to the bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.
Renewal and term
The premium covers a one-year term from the effective date you choose.
Renew before the expiry date to keep the bond in force: the license, permit or contract it backs expects continuous coverage.
How to file it
File with CTDOT / OSTA. Submit the executed bond with your major traffic generator certificate. Wet-ink originals mailed when CTDOT insists.
What sets the price
