NOTICE TO ALL BIDDERS : All bids over $150,000.00 must use two-way electronic bidding.

Two-way Electronic Bidding (1)
Two-way electronic bidding does not require hard copy bids to be submitted. It is preferred by more than two-thirds of contractors. 

Mn/DOT has used a third-party Web site Bid Express ( for two-way electronic bidding since 2001. 

Mn/DOT, in conjunction with Bidx, uses the Expedite 5.9a program (spreadsheet application) in the two-way electronic bidding process.

Access Bidx to register and create an account.  Bidx charges a monthly fee to use their secure Web site.  By registering with Bidx, you will learn how to submit your bid and bid bond. 

Electronic Bid Bonds
Contact your bonding agent to obtain an electronic bid bond and bid bond code.  Submit bid bond codes with your electronic bid.  Hard copy bid bonds are also acceptable.


  • Checks and balances within the software program ensure less chance of errors
  • Bidder enters only the unit prices; quantities and item descriptions are provided by Mn/DOT
  • System completes calculations based on data entered by the contractor and automatically checks for errors or omissions
  • Faster determination of the low bidder and faster posting of bid results
