The Social Democrat-Green coalition government froze construction of the Stockholm Bypass project in October and has pledged to close Bromma Airport by 2022.
However, a majority of opposition politicians in the parliament's traffic committee backed the motions put forth by the previous four-party centre-right Alliance government.
The committee said the construction of the bypass must resume by the start of next year and that the government should not appoint a negotiator to consider the closing of Bromma.
"I assume that the government will follow the decision of parliament," Moderate party parliamentarian Lars Hjälmered told news agency TT.
The full parliament is expected to vote on the committee's proposals on December 19.
