Interim Management Statement

3i Infrastructure Limited ('3i Infrastructure' or 'the Company') is an
investment company focussing on infrastructure investment opportunities
globally. This Interim Management Statement is issued in accordance with FSA
Disclosure and Transparency Rule 4.3. This statement relates to the period from
30 September 2007 to 31 December 2007.

Peter Sedgwick, Chairman of 3i Infrastructure, said: '3i Infrastructure
continues to make good progress towards achieving the return objectives set out
at its IPO. The assets in the Company's portfolio are generating returns in line
with expectations and the Board is encouraged by the flow of investment
opportunities presented by the Investment Adviser.'

Michael Queen, Infrastructure Managing Partner of 3i Investments plc, Investment
Adviser to 3i Infrastructure, added: 'In current volatile markets,
infrastructure's defensive characteristics make it a particularly attractive
asset class.  While the availability of credit continues to tighten across many
sectors, infrastructure assets remain relatively attractive to debt providers
due to their stable return profile.  We are continuing to identify high quality
investment opportunities that can deliver 3i Infrastructure's stated
objectives.'


1. Investment activity

3i Infrastructure invested £442 million in the period from incorporation on 16
January 2007 to 31 December 2007, of which £30 million has been invested since
30 September 2007. Investment since 30 September 2007 relates mainly to the
US$51 million (£25 million) draw-down of commitments to the 3i India
Infrastructure Fund in November 2007 to fund its investment in Soma Enterprise
Limited ('Soma'). Soma is a leading player in the infrastructure construction
industry, specialising in multi-disciplinary engineering, procurement and
construction contracts and increasingly on developing build-operate-transfer
projects. A further £5 million of investment has been made into Infrastructure
Investors LP (I2), a leading investor in secondary PFI projects in the UK and
continental Europe, to fund the acquisition of two projects.

As set out in 3i Infrastructure's Prospectus, the Company was granted an option
by 3i Group plc ('3i Group') to acquire all of 3i Group's limited partnership
interests in the Alma Mater fund, active in the design, construction, financing
and operation of university accommodation facilities in the UK. On 31 December,
the Company elected to exercise the option. An independent valuation of 3i
Group's interest in the Alma Mater fund is currently being performed. Once the
value has been determined the Company will have the right to withdraw the
exercise of its election.


2. Returns

3i Infrastructure is making good progress towards achieving the return
objectives set out at its IPO, building on the Interim results announced on 22
November 2007. The assets in the Company's portfolio have continued to perform
in line with expectations.


3. 3i India Infrastructure Fund

3i Group announced the first close of the 3i India Infrastructure Fund ('the
Fund'), at US$500 million in September 2007, with 3i Group and 3i Infrastructure
having committed US$250 million each at that time. On 24 January 2008, 3i Group
stated in its Interim Management Statement that it expects to announce a final
close of the Fund by the end of March 2008 and that the target size of the Fund
is US$1 billion. Of 3i Infrastructure's US$250 million commitment, US$165
million had been drawn down at 31 December 2007 to fund investments by the Fund
in Adani Power Private Limited and Soma.

As new investors are admitted into the Fund before or at the final close, part
of the amounts drawn down from 3i Infrastructure will be returned to the Company
in order to apportion the Fund's investments proportionately between all
investors, based on each investor's commitment to the Fund. Any such amounts
returned to 3i Infrastructure will remain committed to the Fund, available for
draw-down as and when new investments are to be made by the Fund.
