column1      column2       column3
1.1            1           Eastern express highway
1.1            2            weater way
2.1            0            water
2.1            2            land

なぜこのようにしたいのかわかりませんが、これはあなたのサンプルではうまくいきます。試す

SELECT
  substring(section,1,3) as column1,
  CASE WHEN LEN(section)<5 THEN '0'
  ELSE
     SUBSTRING(section,5,1)
  END as column2
FROM MyTable
