This section requires that any money counties receive from the Highway Users Tax Fund must go into a special account called a "road fund." This is set up by the county's board of supervisors to be used for expenses related to roads. Additionally, if the county earns interest by investing this money, that interest must also stay in the road fund and be used solely for road-related purposes.

This law allows county boards of supervisors to use money from their road funds to work on streets, bridges, and culverts in cities within their county, but only if the city governments agree to it. The board must set rules about how this money will be allocated and spent.

This law states that counties cannot use funds to build or improve highways or streets with patented or branded paving materials unless the project is given to the lowest responsible bidder after considering alternative bids for non-patented materials. However, patented materials can be used for maintenance if the road was originally built with such material and it's deemed impractical to use anything else.

This law allows a county's board of supervisors to spend money from their road fund on building or improving public highways outside their county borders. They can do this if there's an authorization from the board of the county where the highway will be built, or under a contract for state highway projects.

This section allows a county's board of supervisors to take steps for highway construction once they have the necessary authorization. They can either use their own resources or transfer funds to either a state commission or the U.S. Secretary of Agriculture. Any funds transferred must be used strictly for the highway project as specified in their resolution.

This law gives county boards in California the authority to work on highways that run along or cross county borders. This includes building, improving, fixing, or maintaining these highways.

Counties can buy land or necessary right-of-ways to complete these projects. They can also partner with neighboring counties, even across state lines, to share responsibilities for these highways.

The law allows these boundary highways to be treated as regular county highways, meaning funding can come from the state's Highway Users Tax Fund.

This law allows the board of supervisors in a county to create a special fund, called a county highway right of way acquisition revolving fund, to buy or acquire land needed for county highways. The board needs a four-fifths majority to approve this. The amount of money in this fund can't be more than 0.5% of the county's assessed property value at any time.

This law allows a county's board of supervisors to propose an election where voters can authorize the county to issue and sell bonds.

The purpose of these bonds is to raise money for obtaining the land needed to build or improve county highways. For the bonds to be issued, two-thirds of the voters must approve them during the election.

The total amount of bonds issued cannot exceed 0.5% of the county's current assessed property value.

This law allows the county's board of supervisors to put money into a special fund dedicated to acquiring land for county highway projects. They can use any available funds meant for county highway purposes to do this.

This law allows the board of supervisors to choose any suitable way to pay for the different stages of dealing with the county expressway system. This includes planning, designing, building, upgrading, maintaining, and running the system.
