             9 1/2% Senior Notes Due 2015

Ladies and Gentlemen:

         We refer to the Registration  Statement on Form S-4 (the  "Registration
Statement")  being filed by American  Commercial  Lines LLC, a Delaware  limited
liability company ("ACL"),  and ACL Finance Corp., a Delaware  corporation ("ACL
Finance," and together with ACL, the "Issuers"),  and certain  affiliates of the
Issuers named therein as guarantors and listed on Exhibit A attached hereto (the
"Guarantors")  with the Securities and Exchange  Commission  (the  "Commission")
under the Securities Act of 1933, as amended (the "Securities Act"), relating to
the registration of $200,000,000  principal amount of the Issuers' 9 1/2% Senior
Notes Due 2015 (the "Exchange  Notes"),  which are to be offered in exchange for
an equivalent principal amount of currently  outstanding 9 1/2% Senior Notes Due
2015  (the  "Old  Notes"),  all as  more  fully  described  in the  Registration
Statement.  The Old Notes were, and the Exchange Notes will be, issued under the
Indenture,  dated as of February  11, 2005 (the  "Indenture"),  by and among the
Issuers,  the guarantors from time to time parties thereto and Wilmington  Trust
Company,  as trustee (the "Trustee").  The Old Notes are, and the Exchange Notes
will be, guaranteed (the "Guarantees") by the Guarantors  pursuant to Article 10
of the  Indenture.  Old Notes that are accepted in exchange  for Exchange  Notes
will be cancelled and retired.

         In rendering the opinions  expressed below, we have examined and relied
upon copies of the Registration Statement,  the Indenture,  the form of Exchange
Notes and the forms of Guarantees. We have also examined originals, or copies of
originals  certified  to  our  satisfaction,  of  such  agreements,   documents,
certificates   and  other   statements  of  governmental   officials  and  other
instruments,  and  have  examined  such  questions  of law  and  have  satisfied
ourselves  as to such  matters  of  fact,  as we have  considered  relevant  and
necessary as a basis for this opinion

letter.  We have assumed the  authenticity  of all documents  submitted to us as
originals, the genuineness of all signatures,  the legal capacity of all natural
persons and the  conformity  with the original  documents of any copies  thereof
submitted to us for our  examination.  In  addition,  we have assumed that there
will be no change in the laws currently  applicable to the Issuers and that such
laws will be the only laws applicable to the Issuers.

         Based  on  the  foregoing,   and  subject  to  the  qualifications  and
limitations set forth below, we are of the opinion that:

         1. ACL Finance and each of the  Guarantors  that is a  corporation  are
duly  incorporated and validly existing under the laws of the State of Delaware.
ACL and each of the  Guarantors  that is a limited  liability  company  are duly
formed and validly existing under the laws of the State of Delaware.

         2. The Exchange Notes have been duly  authorized by each of the Issuers
and the Guarantees have been duly authorized by each of the Guarantors.

         3. Upon effectiveness of the Registration Statement, as finally amended
(including  all  necessary  post-effective   amendments,   if  any),  under  the
Securities Act,  qualification of the Indenture under the Trust Indenture Act of
1939,  as amended (the "Trust  Indenture  Act"),  execution  and delivery of the
Exchange Notes by the proper officers of the Issuers,  authentication thereof by
the Trustee in  accordance  with the  provisions of the Indenture and receipt of
the Old Notes by the Issuers in exchange  for the Exchange  Notes,  the Exchange
Notes will be duly  authorized  and issued by the  Issuers  and will  constitute
valid and binding obligations of the Issuers except to the extent enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent  transfer  or  other  similar  laws  relating  to  or  affecting  the
enforcement  of  creditors'  rights  generally  and by  the  effect  of  general
principles of equity  (regardless of whether  enforceability  is considered in a
proceeding in equity or at law).

         4. Upon effectiveness of the Registration Statement, as finally amended
(including  all  necessary  post-effective   amendments,   if  any),  under  the
Securities  Act,  qualification  of the Indenture under the Trust Indenture Act,
execution  and  delivery  of the  Exchange  Notes by the proper  officers of the
Issuers, authentication thereof by the Trustee in accordance with the provisions
of the  Indenture,  receipt of the Old Notes by the Issuers in exchange  for the
Exchange  Notes and  execution  and  delivery  of the  Guarantees  by the proper
officers of the Guarantors,  the Guarantees  will  constitute  valid and binding
obligations of the Guarantors except to the extent enforceability may be limited
by applicable bankruptcy,  insolvency,  reorganization,  moratorium,  fraudulent
transfer or other  similar laws  relating to or  affecting  the  enforcement  of
creditors'  rights  generally and by the effect of general  principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law).
