Rabbi David Seidenberg has published a variety of resources for Tisha b’Av at his website NeoHasid.org. Among those resources is his translation of Eikha (Lamentations), which begins:

Eikhah! How can it be –
that she sat alone
the city so great / so swelled with people?
She was like a widow.
The one great among the nations,
ministering among the states, became a slave caste…

That translation is available for free download in PDF format:

Eikhah – Laments [pdf]

Edited 2015 to add: there is a new edition available for download at NeoHasid this year.
