I remember helping TDM (I was assigned) preparing the small red book 'Jambatan Bengkok' (The Crooked Bridge) about three years ago.
Its content, among others were letters of correspondence between TDM (as the premier then) and his counterpart in Singapore Mr Goh Chok Tong.
Goh, if I am not mistaken, did not at all object to the construction of the crooked bridge across the Straits of Johore as long as it didnt go beyond our common border. In fact, Goh was supportive of such an idea.
However, many analysts then were more pro-Singapore, including those who are Malaysians. The bridge will, of course, lead to the demolition of the Causeway, enhance the waterway for tourism prospect as it would allow small ships and large barges and yachts to pass underneath, and improves the quality of water for the benefit of Johore fishermen.
Singapore didnt like the idea as it was perceived as an element to jeopardise their economy, notably its shipping. In fact, Port of Tanjung Pelepas will benefit more as smaller ships which can pass the Straits would eventually skip Singapore ports. (read Rockybru...)
When Pak Lah cancelled the project, the Singaporeans were overjoyed. Malaysians stood as losers as we failed to establish its economic potential.
Now that Najib wanted to revive it, the Republic was feeling the threats coming again. With the demolition of the Causeway, their worries are for the possibilities of water supply agreement with Johore being disrupted or renegotiated over its new price, and the railway link which has played an essential role in ferrying Malaysian 'Singapore-made' product across.
I also remember once the Sultan of Johore had called for the demolition of the Causeway to make way for the bridge.
Well, its not a bridge too far anyway...
