The Takutu River Bridge (Portuguese: Ponte do Rio Tacutu) is a bridge across the Takutu River, linking Lethem in Guyana to Bonfim in Brazil. It was completed in 2009 and opened on 31 July 2009. Its official inauguration was on 14 September 2009, in the presence of leaders of both countries. It cost USD 5 million and was paid for by Brazil. The bridge was a project within the Initiative for the Integration of the Regional Infrastructure of South America.
The bridge is a rare example of a land border where drivers must change from driving on the left (in Guyana) to driving on the right (in Brazil), or vice-versa. The changeover is achieved by means of a crossover bridge.
