Yesterday morning around 8am a cyclist was coming down the overpass from the Custis Trail to the MV Trail (over GW parkway) and apparently hit the steel post at the bottom in the center of the ramp. I talked to the NPS officer and he stated the cyclist was in critical condition. Upon leaving I noted there was some gravel on the lower portion of the ramp which could have been a factor although the officer said that speed was a factor. The officer was going to block the trail off but since he had not blocked the top of the trail at Lee Hwy and Lynn St it would not do much good. I did not read anything in the paper about the accident.
