Answer: a bridge of contract
Step-by-step explanation:
A bridge of contract from the state government. Am I sure the state government before leasing out the land must have asked the company what they wanted to use the land for and for how many duration. It is obvious that duration of the agreement , I.e the duration by which the land was leased was not stated from the passage above but to draw conclusion ,the company will most likely charge the state government based on a bridge of contract agreement as they must have told the state government what they wanted to build and there must have been terms . am alsonsure that if the company actually knew that the government was going to build a bridge on that land in the coming few years, they wouldn't have invested so much in the land . so it a bridge of contract agreement.
