Formula 1's ruling body, the FIA, has decided to raise the elements behind the kerbs of two chicanes of the Monte Carlo circuit for this weekend's Monaco Grand Prix.
The FIA said new, higher elements have been placed after the kerbs at the Nouvelle chicane (Turn 11), as well as the one after the Swimming Pool (Turn 16). The move is aimed at stopping drivers from cutting through them at high speed.
The governing body also said several parts of the circuit have been resurfaced. The pitlane surface is all new, as is the stretch from Ste Devote corner to the junction of Avenue de Monte Carlo.
Also re-surfaced are sections from Place du Casino to the Tunnel du Portier entry and from the tunnel exit to the chicane.
