You risk a fine of between 500 and 5,000 Shillings if you fail to use a designated footbridge when crossing the road. The warning come as NTSA steps up its crackdown on pedestrians who fail to use designated footbridges when crossing the road. Several pedestrians were arrested today morning at the General Motors footbridge along Mombasa Road for crossing at undesignated points and obstructing the free flow of traffic. The suspects were arrested a day after 38 others were arrested yesterday over failure to use a foot bridge in Buruburu.
