In the Philippines, a proposal has been made for the Tarlac-Pangasinan-La Union Expressway (TPLEx) to be extended. The US$441.6 million project is for a 59.4km extension to the TPLEx route. The proposal has been put forward by San Miguel Corp (SMC). The highway extension would help improve transportation to the north of Manila, the capital of the Philippines. The work would extend the route to San Juan from Rosario. The work would be carried out in three stages, with one 18.4km section between San Juan and Naguilian, a 23km stretch from Naguilian to Tubao and an 18km section between Tubao and Rosario.
