accordingly:
	SECTION 3.____.  The change in law made by this Act to 
Subchapter E, Chapter 228, Transportation Code, applies only to a 
contract for the construction of a highway or segment of a highway 
that the Texas Department of Transportation enters into on or after 
the effective date of this Act.  A contract for the construction of 
a highway or segment of a highway entered into before the effective
