A walk along the two kilometers of light rail that Lagos authorities have managed to build in three years gives a sense of how hard it is to impose order on one of Africa's most chaotic cities.
From either side of the concrete structure - no track has yet been laid - the crowded slums and highways of Nigeria's lagoon-side commercial hub teem with activity.
Its trademark yellow buses overtake, undertake and force their way down impossibly narrow side streets, where women stir pots next to canals clogged with rubbish.
With between 15 million and 21 million people - the upper estimate is the official one, though no one really knows - and generating a third of GDP for Africa's second biggest economy, Lagos has become almost as alluring to yield-hungry investors as it is to the 4,000 or so economic migrants who turn up each day.
Violent crime, mushrooming slums, police extortion and widespread fraud have often held investment back, but in the past decade, authorities have started trying to tackle some of the obstacles, especially maddening traffic bottlenecks.
