"Black bridge" is a method of loan financing. The specific meaning may vary depending on the region and industry, but generally speaking, it refers to a bridge loan.

In loan financing, sometimes borrowers already have a loan that is about to expire and need to be repaid, but they do not have enough funds to repay it temporarily, so they apply for a new loan from another bank or lending institution. and use the new loan to pay off the old loan. During this process, the issuance of new loans usually requires meeting certain conditions and procedures, such as mortgages or guarantees, and the loan amount and interest rate may also be higher.

The term "crossing the bridge" may originate from this process, because this method of loan financing may involve underground financial institutions or informal financial activities such as loan sharking, so it is called "crossing the bridge".
