If the appropriation made in any year by the board of chosen freeholders for the repair of the road and the lighting plant connected therewith shall be insufficient, in the judgment of the boulevard commission, to put and keep them in proper condition, it may from time to time make requisition in writing on the board of chosen freeholders for the money necessary to enable it to put and keep such road and lighting plant in good repair.

The board of chosen freeholders may cause the money to be raised and collected wholly or partly by taxation, or may in its discretion, issue bonds for that purpose in an amount not to exceed fifty thousand dollars.
