Quick takeaways

About contracting with the Department of Transportation

Signed into law by President Biden in November 2021, the Bipartisan Infrastructure Law (BIL) aims to address the country’s aging infrastructure by investing in our built environment. The Department of Transportation received a significant portion of BIL funding to improve roads, bridges, and public transit among other critical transportation infrastructure. 

The Federal Highway Administration, Federal Transit Administration, and National Highway Traffic Safety Administration will seek to allocate at least 10% of their more than $370 billion in contract authority to small, disadvantaged businesses. Small businesses will play a critical role in rebuilding roads and bridges, eliminating the nation’s lead service lines and pipes, deploying broadband, and installing thousands of miles of new and resilient transmission lines.

Nearly $600 billion is being invested in every corner of the country’s transportation infrastructure.

If your small business provides services related to our transportation infrastructure, your firm may be eligible. Needs vary by contract.

How SBA can help your small business

Coaching and training

SBA provides counseling, training, and technical assistance. These are meant to help businesses improve their contracting capabilities. 


SBA guarantees small business loans for payroll and contract start-up costs. These may be relevant for your small business. Ex: Federal contractors typically get paid 45 – 60 days after contract start. Employees are usually paid every 15 days. 

Surety bonds

Surety bonds provide the customer with a guarantee that the work will be completed. This helps small businesses win contracts. Many public and private contracts require surety bonds. Surety bonds are offered by surety companies. SBA guarantees surety bonds for certain surety companies. This allows these companies to offer surety bonds to small businesses that might not otherwise get them. Eligible businesses include: 

  • Small businesses according to SBA’s size standards
  • Small businesses with a small contract up to $9M for non-federal contracts and up to $14M for federal contracts
  • Small businesses that meet the surety company’s credit, capacity, and character requirements. 

Find surety bond agencies in your state. SBA also works with DOT on a Bonding Education Program.
