Spa Road Works at Inchicore was the major constructor of trams and buses for Ireland during its years of operation from 1882 to 1977.

The Spa Road Works were founded by William Martin Murphy, founder of the Dublin United Transport Company (DUTC), in 1882 to construct trams.

[1] As the twentieth century progressed the omnibus began to take over from tramways in Dublin, and Spa Road Works migrated into bus production.

From about 1973 CIÉ leased the factory to Van Hool McArdle, a joint venture of Van Hool and Thomas McArdle of Dundalk, who initially continued to build Leyland Atlanteans.

[4][5] Following closure in 1977 tools and equipment were moved to the Bombardier-GAC factory set up in Shannon which produced buses from 1980 until 1986.
