# §661.51. Can TTFBP funds be used for the approach roadway to a bridge?


Yes, costs associated with approach roadway work, as defined in [§ 661.5](/cfr/23/661.5.md) are eligible. Long approach fills, causeways, connecting roadways, interchanges, ramps, and other extensive earth structures, when constructed beyond an attainable touchdown point, are not eligible uses of TTFBP funds.
