National says it won't commit to making the Hawke's Bay Expressway four lanes if elected in 2020, but the project remains something it is interested in.
The party made a promise to four-lane the expressway before the 2017 election, but both its transport spokesman Chris Bishop and Tukituki MP Lawrence Yule say the promise hasn't been softened.
National announced on Monday 10 projects being considered under the second generation of its roads of national significance project.
Making the Napier to Hastings section of the expressway four lanes is one of the options, with Bishop saying more information will be released in 2020.
Bishop said people in Hawke's Bay should not see it as a softening of Bill English's pre-2017 election promise.
