Lagos State Sector Commander of FRSC, Olusegun Ogungbemide, gave the warning on Monday in a statement in Lagos.
Ogungbemide said that the Third Mainland Bridge was still under repairs and the diversion plan earlier issued to motorists must be strictly adhered to.
He said that the Corps was disturbed by the recent disruption of law and order where motorists drove against traffic.
“Motorists should note that orderliness has been restored on the Third Mainland Bridge and other parts of the state.
“Motorists are advised to obey all traffic rules and regulations by abstaining from driving against the flow of traffic ‘One way’ to avoid crash and head on collision.
“Alternative routes for Mainland bound motorists are: Osborne Road Ikoyi to Carter Bridge can access Eko Bridge through Ijora Olopa to Funsho Williams Avenue.
“Also Dormanlong Bridge to Ikorodu or use Carter bridge to Iddo through Oyingbo to Herbert Macaulay. One can also pass through Jibowu to link Ikorodu road then connect your destination.
“From Ozumba Mbadiwe Road you can link Falomo Bridge through Alfred Rewane to Awolowo Road or Osborne Road to Iluburin connect Carter Bridge can be used by motorists moving from Victoria Island to access Mainland,”
