Simple. The Romans were and still are the best architects and builders of all times. there are roman bridges, aqueducts and roads still in use today.
take a look at the bridges of New York City, many were built in the 1950's & 1960's and they now need extensive repairs that will cost as much as building a new bridge.
Roman bridges lasted 2,000+ years while modern bridges barely make it to 50 years.
The invented concrete, which formed the basis of walls and domes, with the Greek columns as a decorative adjunct rather than the basis of the structure.
They invented cement, the arch, and the dome.

Usually concrete. Romans invented concrete.
Columns were an important architectural element in both the Roman and Greek cultures but the two groups used them differently. While the Greeks favored the Doric and Ionic style of column, the Romans liked the Corinthian and the Composite styles. The Greeks surrounded their temples and public buildings with a ring of columns but the Romans only used them in the front of their buildings. Another difference was in the materials used to build private homes. the Romans used durable materials such as brick and stone; the Greeks used stone for the foundations of their houses, but constructed the upper floors and inner walls of mud brick, which have not endured over time.
The Romans greatly admired the art and architecture of Greece, as well as many of their ideas. Roman art is not really the same as Greek art, but the Romans did copy the Greeks. One notable copy is the column. The Greeks used solid marble 'drums' to build their columns, the Romans built theirs with brick, faced with cement to resemble the Greek columns. .Roman art is more naturalistic and less stylized then Greek art. Greeks were most interested in idealism Romans were more interested in realism.
